Background Primary open angle glaucoma (POAG) is a major blindness-causing disease,characterized by elevated intraocular pressure due to an insufficient outflow of aqueous humor. The trabecular meshwork lining the aqueous outflow pathway modulates the aqueous outflow facility. To study the biological characteristics of the trabecular meshwork cells has important significance. Objective This study was to culture the trabecular cells from primary open-angle glaucomatous eye (POAG) and study the biologic characteristics of passaged cells. Methods The deep scleral tissue with trabecular meshwork was obtained during the trabeculectomy from 8 eyes with POAG. The trabecular cells were primarily cultured and passaged in vitro. The generation 3 cells were identified by immunochemistry with the laminin (LM), fibronectin (FN) and neuron specific endolase (NSE)monoclonal antibodies. The ultrastructure was examined to observe the biological characteristics of the cells under the transmission electronic microscope. The experimental results were compared among POAG group, normal control group and blank control group. Results The primarily cultured POAG trabecular cells migrated from the edge of tissue mass about 10 days. The cells of generation 3 presented the logarithmic phase in the first 4 days and fused in the 7th day. FN,LM and NSE were positively expressed in the generated cells in POAG group and normal control group rather than blank control group. The MOD values of the generation 3 cells for FN in POAG group and normal control group were 0. 35 ± 0.06 and 0. 26 ± 0. 01, and those for LM were 0. 34 ± 0. 03 and 0. 25 ± 0. 02 respectively, showing statistically significant difference between these two groups ( FN: t = 14. 446, P＜0.001; LM: t = 9. 346, P＜0. 001 ). The microvilli, cytolysosome and phagocytic vesicle were obviously decreased in the trabcular cells of POAG group compared with normal control group under the transmission electron microscope. Conclusion The trabecular meshwork cells from POAG can be successfully cultured and passaged in vitro. It provides a cytology basis for further glaucoma research.

Objective To evaluate the efficacy and safety of levetiracetam (LEV) monotherapy on children with epilepsy.Methods Forty-one children (26 cases were male,15 cases were female) with epilepsy aged 7 months to 13 years were treated with LEV as monotherapy.These patients were selected from Department of Neurology ,Wuhan Children′s Hospital, from Aug.2007 to Aug.2009.The starting do-sage of LEV was (13.6?4.7) mg?kg-1?d-1,twice daily,and its objective dosage was (25.7?7.5) mg?kg-1?d-1,twice daily.LEV monotherapy was investigated by a self-controlled and open-label research,and the follow-up period ranged from 6 months to 2 years.Results The effective rate was 68.3% (28 cases),with 39.0% (16 cases) achieving seizure freedom in LEV monotherapy of children with epilepsy.Thirteen patients (31.7%) had poor efficacy in reduction of seizures,7 patients (17.1%) discontinued LEV monotherapy due to either an inadequate seizure control or aggravated seizures.Fifteen patients (36.6%) had the therapy-related adverse events in LEV monotherapy,including gastrointestinal dysfunction (5 cases),irritability (5 cases),dizziness (2 cases) and somnolence (2 cases).The adverse effects appeared in 2-4 weeks of early LEV therapy and were spontaneously disappeared in 1 week to 1 month of continuing therapy.Conclusions The LEV monotherapy is effective and safe for the control of partial and generalized seizures in children with epilepsy.LEV appears to be a broad-spectrum,first-line anti-epileptic drug in treatment of children with epilepsy.

Objective To investigate the clinical characteristics and diagnostic main points of poliomyelitis-like syndrome(PS).Met-hods The clinical data of 15 children with PS were analyzed retrospectively including nervous system manifestation,results of lab andauxiliary examination,diagnosis and reason of misdiagnosis,treatment and progress.Results PS in all 15 children was characterized by mean age of onset(3.3 years),and forerunner infection(in 11 cases,73%)with acute upper respiratory infection of diarrhea 1-2 weeks pre-onset or during onset.All cases were acute flaccid paralysis,12 cases(80%) of which were only one limb.The positive outcome of serologic examination in PS consisted of 4 cases in coxsackie virus-IgM,1 case in EB virus-IgM,1 case in herpes simplex virus-IgM and 1 case in mycoplasma-IgM.All children showed the electromyologram changes in nerve damage.The muscle force of 4 cases increased one grade.Conclusions Children with PS are characterized by the age of onset under 5 years old,acute flaccid paralysis(mostly affected one limb),and the most pathogen being enterovirus.The electromyologram examination can help establish a definite diagnosis in PS.

Objective To explore the risk factors affecting prognosis of children with Tourette syndrome(TS).Methods The follow-up visits were conducted on the clinical data of 98 cases with TS(85 male,13 female;aged 4-16 years old)from 1997 to 2005 in Wuhan children's hospital.All cases were consistent with the diagnostic criteria of TS in the 4th edition of Diagnostic and Statistical Manual of Mental Disorders(DSM-Ⅳ).The investigations were performed by the investigators who received special training using the unified questionnaire with the methods of direct inquiry or by telephone.The factors included sex,age,severity of TS,the primary symptoms,family history,coexisting diseases,basic diseases,perinatal abnormity and family-social relations.The prognosis of TS and these factors were analyzed by linear regression and stepwise regression with SPSS 12.0 software.Results About 16 cases lost follow-up and the other 82 cases with follow-up(72 male and 10 female)received retrospective review.They were 14 to 25 years old with complete data,and 50 cases healed,32 cases not healed.Results from non-conditional simple variant Logistic regression showed that such cases were associated with the following factors:age,family history of TS,severity of TS,coexisting diseases,basic diseases and perinatal abnormity(Pa0.05).Out of 6 suspicious factors,there were coexisting diseases(OR=84.088,95%CI 10.850-651.682),severity of TS(OR=13.956,95% CI 2.412-80.762),and family history of TS(OR=27.127,95% CI 1.047-702.831)of risk factors.Conclusion The long-term prognosis of children with TS may be related with coexisting disease,severity of TS and family history respectively.

Studies have shown that women's menopause caused by permanent cessation of ovarian function is closely related to lipid metabolism disorders. Er-xian Decoction has been used in the clinical treatment for gynecological diseases and has a good effect on diseases related to reduced sex hormone function. In this study, metabolomics was performed on bilateral ovariectomized model rats within 12 weeks after modeling to mimic the physiological state of menopausal women in different menopausal stages and Er-xian Decoction dosed model rats. The results of liver oil red O staining sections showed lipid metabolic disorder of bilateral ovariectomized model rats and the regulating effects of Er-xian Decoction. 46 potential biomarkers (6 steroid hormones, 3 sphingolipids, 11 phospholipids and 26 glycerides) in plasma and 32 potential biomarkers (1 steroid hormones, 20 phospholipids and 11 glycerides) in liver were obtained based on lipidomics analysis. Then, we analyzed the differential metabolic pathways and construct the lipid metabolism network significantly regulated by Er-xian Decoction. The results provided valuable information for in-depth understanding of the gradual changes on lipid metabolism disorders under menopausal conditions and the characteristics and mechanisms of compound Er-xian Decoction's regulatory effects. The study complied with the procedures established by the Animal Experiment Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences and passed the animal experiment ethics examine (No. 00000918).
