The occurrence of epilepstic seizures in patients with cerebral palsy (CP) remains a serious event and is very disruptive for children who already suffered from orther disabilties. Data from population-based studies or neurodevelopmental clinic studies showed that 8%～62% of patients with CP suffer from epilepsy. The incidence is highest in spastic tetraplegia and hemiplegia. Half of the patients were onset within the first year of age. Children with tetraplegia CP tended to have an earlier onset of epilepsy than chlidren with other CP types. Partial seizures were the most common seizure types, followed by infantile spasms and Lennox-Gastaut syndrome. Low birth weight, neonatal seizures, family history of epilepsy, lower intelligence and grey matter damage were found to be related to significantly increased risk of epilepsy. Epilepsy in children wih CP usually had poor outcome, half of them were intractable and needed polytherapy. Only 37%～65.2% of patients became seizure-free.

Objective The aim of the study is to explore the efficacy of Carbamazepine with manual massage on grand mal epilepsy.Methods Using a prospective research method,the grand mal epilepsy patients were randomly divided into the experimental group(40 cases)and the control group(40 cases).The experimental group was given manual massage based on oral Carbamazepine treatment.The control group was given oral Carbamazepine treatment.The treatment effect was compared between two groups.Results The curative efficacy of the experimental group was 92.5％,higher than 80.0％ of the control group.Conclusions Carbamazepine with manual massage for treatment of grand mal epilepsy can obviously improve curative efficacy,which is worthy of popularization and application.

Objective To discuss the etiology, clinical features and prognosis of non benign neonatal arrhythmias. Method Clinical data of 27 cases of non benign neonatal arrhythmias diagnosed from January 2005 to January 2010 were retrospectively analyzed. Results Among 27 neonats, there were 15 male and 12 female. Fourteen cases were early neonatal and 13 were late neonatal. Gestational age was less than 32 weeks in 6 cases, and more than 32 weeks in 21 cases. In 19 cases with tachyarrhythmia, 14 cases were induced by respiratory infection. The causes of 8 newborns with bradycardia arrhythmia were congenital heart disease (3 cases), electrolyte disturbance (2 cases), severe asphyxia with sepsis (2 cases), and severe asphyxia (1 case). The onset age and gestational age were lower in cases with bradycardia arrhythma that those in cases with tachyarrhythmia (P<0.005). The cure rate and effective rate of tachyarrhythmia was 89.5%and 100%, of bradycardia arrhythmia was 0%and 12.5%, respectively, and the differences were signiifcant (P<0.005). Conclusion Clinical characteristics, pathogenesis and prognosis were different between tachyarrhythmia and bradycardia arrhythmia in neonates.

Objective To explore the thyroid function changes of episodes period and remissions period in children with primary nephrotic syndrome (NS).Methods The urinary protein quantitation and serum albumin,total cholesterol,thyroid hormone level [total triiodothyronine (TT3),total thyroxine (TT4),free triiodothyronine (FT3),free thyroxine (FT4) and thyroid stimulating hormone (TSH)] of episodes period and remissions period in 15 children with primary NS were retrospectively analyzed.Results There were statistical differences in urinary protein quantitation and serum albumin,total cholesterol in children with NS between episodes period and remissions period (P ＜ 0.05).The TT3,TT4,FT3,FT4 in episodes period were significantly lower than those in remissions period [(0.6 ± 0.3) μ g/L vs.(1.3 ± 0.3) μ g/L,(40.0 ± 23.0)μ g/L vs.(68.0 ± 15.0) μ g/L,(1.6 ± 0.3) pmol/L vs.(3.3 ± 0.3) pmol/L,(8.6 ± 2.5) pmol/L vs.(12.2 ± 2.0) pmol/L],TSH was significantly higher than that in remissions period [(5.6 ± 2.1) mU/L vs.(2.5 ± 1.1) mU/L],there were statistical differences (P ＜ 0.05).Conclusions Thyroid function of episodes period in children with primary NS is decreased temporarily,associated with heavy proteinuria leads to thyroid hormone missing from urine.Detecting thyroid function plays an important role in estimating the state and guiding the treatment of primary NS.

Background Proliferative vitreoretinopathy (PVR) is one of the major causes of retinal detachment surgery failure.Based on proteomic studies of PVR vitreous,the insulin-like growth factor binding protein-6 (IGFBP-6) protein was specifically expressed in the vitreous and serum of PVR patients.Furthermore,its expression level is higher in the vitreous and serum in severe PVR patients than that in mild PVR patients.Objective This experiment was to detect the expression of IGFBP-6 in a PVR rat model.Methods Seventy 7-week old male SPF Wistar rats were included and were randomized into the PVR model group and control group.A mixture of RPE-J cell suspension(5 μl) and platelet-rich plasma (5 μl) was intravitreally injected in the left eyes of adult Wistar rats to establish the PVR model,and normal saline solution was administered in the same way in the control group.The rat eyes were clinically examined 1 week,2,3 and 4 weeks after injection,and PVR was graded based on the criteria of Francine.The animals were sacrificed after 1 week,2,4 or 8 weeks for the preparation of retinal sections and liver extraction.Expression levels of IGFBP-6 mRNA in the rat retina and liver were assayed by real-time Q-PCR.The expression of IGFBP-6 protein in the rat serum and vitreous was detected by ELISA.The use of animals complied with the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results Purified IGFBP-6 RNA was extracted from the liver and retina of Wistar rat and quantified by real-time Q-PCR.The expression level of IGFBP-6 mRNA in retina was (3.79± 1.33) × 10-4 in the PVR model rats,showing a significant decline in comparison with the control rats with a level of(8.32±2.96) × 10 4,4 weeks after injection (t =3.42,P＜0.01).The expression of IGFBP-6 mRNA in the 4th week was significantly lower than that of 1 week,2 or 8 weeks after the establishment of the PVR model(P＜0.05).No significant difference was found in the IGFBP-6 mRNA level in the liver between the PVR group and control group(27.60± 14.01 × 10 4 vs.25.01 ± 12.04 ×10-4,respectively),as well as among the different time points(P＞0.05).IGFBP-6 mRNA content in the retina was significantly reduced in grades 1,2 or 3 of the PVR groups compared with the control group(P＞0.05),but there was no significant difference among the different grades of PVR groups (P＞0.05).Concentrations of IGFBP-6 protein in grades 1,2 and 3 of the PVR model group were (221.00 ± 19.32),(229.63 ± 18.89) and (225.70 ± 26.71) μg/L,with a significant elevation in comparison with (173.25 ±21.11) μg/L of the control group (t =2.14,P＜0.05).However,there was no significant change among the different grades of PVR groups(t=1.24,1.46,P＞0.05).The concentrations of IGFBP-6 protein in the vitreous and serum were higher in PVR rat samples (vitreous:225.44±19.36 μg/L;serum:108.48 ± 15.78 μg/L) than in control rats (vitreous:173.25 ± 21.11 μg/L,serum:95.96 ±17.40 μg/L)(P＜0.05).Conclusions The concentrations of IGFBP-6 protein in the vitreous and serum increase in PVR rats.The results indicate that the increased IGFBP-6 in the vitreous might be a localized autocrine secretion of the eye.

Abstract? AIM: To investigate changes of anterior chamber parameters after posterior chamber phakic implantable collamer lens ( ICL ) surgery and its correlation with intraocular pressure ( IOP) .?METHODS: This was a retrospective case series study. Seventy four eyes in 43 myopia patients were examined by Allegro Oculyzer anterior segment tomography to obtain the changes of anterior chamber volume ( ACV ) , anterior chamber angle ( ACA) , central anterior chamber depth ( ACD) and vault, meanwhile, to measure the IOP to analyze the correlation with anterior chamber parameters.?RESULTS: Compared with preoperative, ACV, ACA, ACD all decreased apparently ( P <0.01 ) in the postoperative period of 1, 3, and 6mo.ACV, ACA and ACD showed their stability in each period after the surgery.There were changes of vault in 1 and 6mo ( t=27.66, P=0.01).IOP had not altered when compared with the preoperative.This research revealed that IOP had no relation with ACV, ACA, ACD and vault in every phase( all P>0.05).?CONCLUSION:For patients underwent ICL, the anterior chamber parameters all decreased which included ACV, ACA, ACD, and had stabilized since early postoperative period. Correspondingly, IOP was stable and had not correlate with ACV, ACA, ACD and vault, however the long-term observation is still necessary.
