Objective: To optimize the formula of memantine hydrochloride sustained release pellets and investigate the drug release in vitro.Methods: Memantine hydrochloride sustained release pellets were prepared by a fluidized bed.The factors such as inlet air temperature, spray pressure and feeding rate were optimized by orthogonal tests.The Box-Behnken response surface methodology was used to screen the major influencing factors (ethyl cellulose aqueous dispersion, PEG 6000 and the coating weight) in the release of memantine hydrochloride.The coating formula and coating weight were optimized with the cumulative release rate of memantine hydrochloride in 2, 6,and 12 h as the response values.The drug release in vitro was also studied.Results: The optimum preparation parameters of the pellets were as follows: the inlet air temperature of 45℃, the spray pressure of 1.0 bar, and the feeding rate of 1.5 r·min-1.The best sustained release coating formula was as follows: the content of ethyl cellulose aqueous dispersion of 8.4%, the content of PEG 6000 of 2.3%, and the weight gain of sustained release layer of 16.7%.The memantine hydrochloride sustained release pellets had notable sustained release effect.Conclusion: Orthogonal tests and Box-Behnken response surface method can be used for the formula optimization of memantine hydrochloride sustained-release pellets.The established fitting model is simple with good predictability.

Objective To summarize the clinical and electroencephalography(EEG) characteristics of benign epilepsy with centro-temporal spikes (BECTS) in children.Methods The clinical manifestations,EEG findings,response to drug treatment and prognosis of 35 children with BECTS from Jul.2003 to Dec.2008 in the First Affiliated Hospital of Zhengzhou University were analyzed retrospectively.Results In the 35 cases,the age of onset was 2.5 to 14.0 years old,and the peak age of onset was 6-10 years old(62.9%).Twenty-two cases mainly presented partial seizures:hemifacial convulsions,sialorrhea,sounds,limb tonic-clonic seizures,and secondary generalized seizures.Thirteen cases were only describled generalized tonic-clonic seizures.Seizures were closely related to sleep and almost occurred shortly after falling asleep or before waking up.There were 26 cases who displayed convulsion during sleeping,including noon break.The EEG features showed numerous or single spikes on one side or both sides in the central and temporal areas under the background of normal activity in interictal period.The release frequency of abnormal wave was significantly increased after falling asleep,so the EEG monitoring during sleep could improve the positive rate of BECTS.Monotherapy with low-dose anti-epileptic drug could obtain good efficacy.Twenty-five cases stopped seizures within 3 months after therapy.Thirty-three cases hadn't get seizure since drug therapy at the age of 16 years old.So far,12 cases had been stopped medicine.Conclusions BECTS mostly begins at school-aged children,which displays partial seizures or secondary generalized seizures.The seizures are closely related to sleep.EEG monitoring during sleep which shows numerous or single spikes on the centrotemporal area has crucial diagnostic value to BECTS.There is a positive response to monotherapy with low-dose anti-epileptic drug and generally the prognosis is good.

Objective To explore the effect of Tuina combined with Traditional Chinese exercise (TCE) on nonspecific chronic neck pain (NCNP). Methods 80 eligible patients were recruited in our hospital from October, 2014 to October, 2015. They were randomized to observation group (n=40) and control group (n=40). The observation group received Tuina combined with TCE, and the control group re-ceived intermittent cervical traction, 5 times a week for 2 weeks. They were assessed with Visual Analog Scale (VAS) and Neck Disability Index (NDI) before, immediately after intervention, and at 1 month follow-up. Results 77 patients completed the treatment and follow-up. The scores of VAS and NDI significantly decreased after a 2-week intervention (t>9.330, P<0.001) in both groups. The VAS score were sig-nificantly lower in the observation group than in the control group immediately after intervention and at 1-month follow-up (F>8.338, P<0.01). The NDI score was significantly lower in the observation group than in the control group at 1-month follow-up (F=9.053, P=0.004). Conclusion Tuina combined with TCE could relieve pain and improve cervical function in patients with NCNP, which was superior to inter-mittent cervical traction.

Background As a newly developed refractive surgery,femtosecond laser in situ keratomileusis (LASIK) receives more and more attention.Changes in ocular stray light after femtosecond LASIK is an important problem that impacts visual quality.Some relevant research has been performed before,but the outcomes are conflicting.Objective This primary study was to investigate the change of stray light values before and after femtosecond LASIK and analyze the relevant factors underlying the change.Methods Clinical data from 109 eyes of 55 myopic patients who underwent femtosecond LASIK in Tianjin Eye Hospital from December,2010 through February,2011 were included in this study.Stray light values were measured and recorded by C-Quant stray light meter preoperatively,and 1 day,1 week,1 month and 6 months postoperatively.The stray light data were compared by repeated measures ANOVA,and the correlations among the stray light values with preoperative factors,such as age,equivalent sphere,pupil diameter and central corneal thickness(CCT),as well as with postoperative factors,such as residual bed thickness(RBT),RBT/CCT,ablation depth,ablation ratio,flap thickness,flap diameter flap base width and exiting energy,were analyzed statistically.Written informed consent was obtained from each individual at initial of this study.Results The stray light values were 0.90±0.19,1.10±0.19,1.02±0.18,0.96±0.16 and 0.94±0.15 pre-operation,and 1 day,1 week,1 month and 6 months after femtosecond LASIK.The stray light values increased significantly 1 day,1 week,and 1 month after surgery,showing significant differences among the various time points (F=17.699,P=0.000).The mean stray light value was higher in 1 week than that in 6 months after operation (t=2.412,P=0.017).No significant differences were found in the stray light values between 6 months and 1 month or pre-operation (t =0.779,P =0.437 ; t =-1.877,P =0.062).No significant correlations were seen between preoperative and postoperative stray light values with age,preoperative refractive diopter,pupil diameter or CCT (P＞0.05).The changes in stray light values 1 week,1 month and 6 months after surgery were negatively correlated with ablation depth(r=-0.226,-0.228,-0.241 ;P＜0.05) and ablation ratio(r =-0.149,-0.219,-0.255 ;P＜0.05).Conclusions Stray light values increase within 1 month and return to normal 6 months after femtosecond LASIK.Stray light values may be related to multiple setting laser parameters and factors during femtosecond LASIK.

ObjectiveTo study the state of oxidative injury induced by sodium arsenite(NaAsO2) in SV-40-immortalized normal uroepithelial (SV-HUC-1 ) cells.Methods SV-HUC-1 cells were exposed to different concentrations of NaAsO2[0(control),1,2,4,8,10 μmol/L] for 24 h,intracellular reactive oxygen species (ROS) was determined by flow cytometry,and the content ofintracellular nitrotyrosine(NT) and the 8-Hydroxydeoxyguanosine (8-OHdG) levels of cell culture medium were detected by enzyme linked immunosorbent assay (ELISA).Results After 24 h treatment,ROS levels(81.76 ± 4.91,95.23 ± 2.17,126.61 ± 17.95,126.74 ± 27.77,114.18 ± 9.65) of SV-HUC-1 cells in the 1,2,4,8,10 μmol/L NaAsO2 exposure groups were significantly higher than those of the control group (69.84 ± 1.28,P ＜ 0.05 or ＜ 0.01 ),ROS levels and exposure dose were positively correlated significantly(r =0.818,P＜ 0.01); the content of NT in the 10 μmol/L NaAsO2 exposure group[(919.66 ± 206.33) μg/L] was significantly higher than that in the control group[ (238.19 ± 38.28)μg/L,P ＜ 0.01 ],NT content and dye concentrations of arsenic also had dose-response relationship (r =0.617,P ＜ 0.01); after 24 h the cells were treated with arsenic,no significant difference of 8-OHdG content in the culture medium was observed(F =2.127,P ＞ 0.05 ).ConclusionNaAsO2 can cause SV-HUC-1 cell oxidative damage.
