Objective To explore the clinical effect of atomoxetine on children with attention deficit hyperactivity disorder(ADHD)comorbid tic disorder.Methods The children who met the criteria of Mental Disorders Diagnostic and Statistical Manual diagnostic criteria for ADHD and tic symptoms were given systematic atomoxetine titration reaching the optimum dose.ADHD and tic symptoms were evaluated with ADHD rating scale-Ⅳ(ADHD-RS-Ⅳ)for parents Yale Global Tic Severity Scale(YGTSS),respectively.Results Twenty children with ADHD comorbid tic disorder [17 male,3 female;age range 7.58-17.0 years,mean age(10.55?2.58)years] completing systemic titration was enrolled in the study,including 10 subjects with ADHD-inattentive type,9 mixed type,and 1 hyperactive/impulsive type.The mean optimal dose was(1.19?0.21)mg/(kg?d).The total score(12.65?9.08)scores,inattention score(7.45?4.75)scores and hyperactivity/impulsivity score(3.0)of ADHD-RS-Ⅳ decreased significantly post-treatment compared with pro-treatment(31.10?8.52,17.60?3.09,and 13.0 scores,respectively,P

Background Sugar cataract is one of the major diabetic complications in the eye,but there is not effective medicine to prevent or delay development of cataract. Objective The goal of this study was to investigate the effects and the potential mechanism of aldose reductase (AR) inhibitor,AL-1576 on prevention of galactose cataract in rats. Methods Forty-two SD rats were randomly and equally divided into 7 groups.The cataracts were induced by feeding with 50％ galactose.At the day of feeding galactose and the day 5,10 and 15 after feeding galactose,AL-1576 was added into the feeds.The rats were divided AL-1576 prevention group and early-,intermediate-or late-stage intervention groups.For another group,the withdrawing AL-1576 group,AL-1576 was added into the feeds at the day of feeding galactose,then was removed after 10 days.The lenses of the rats were examined under the slit-lamp microscope before and after given AL-1576 every 5 days.At the day 35,the lenses were obtained.The wet and dry weight of the lenses were weighted,respectically,to calculate the water content of the lenses.Activities of AR and superoxidedismutase (SOD) and contents of glutathione (GSH) of the lenses were measured by their commercial detecting kits.The care and use of the animals complied with the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission. Results In AL-1576 prevention group,all lenses maintained clear.Opacification of the lenses were significantly attenuated in all three AL-1576 intervention groups and withdrawing AL-1576 group compared with the cataractous model group ( P＜0.05),but the inhibiting role was weaken with late intervention.The water contents and the activities of AR of the lenses were decreased,the contents of SOD and GSH were dramatically increased in all different AL-1576 treated groups compared with the cataractous model group (P＜0.05).Moreover,AL-1576 prevention group showed the best effect on all indexes (P＜0.05). Conclusions The activity of AR can be inhibited by AL-1576 at the different stages of development of cataract induced by galactose.By blocking and attenuating formation of the edema and elevating antioxdative capacity in the lenses,AL-1576 prevents and delays the formation of galactose cataract.

Objective To observe the clinical effectiveness of alprostadil combined to pancreatic kininogenas in the treatment of gerontal diabetic peripheral neuropathy.Methods Totally 90 gerontal patients with diabetic peripheral neuropathy were randomly divided into three groups,the first group received the treatment of mecobalamin,the second group received mecobalamin plus pancreatic kininogenas,the last group received mecobalamin,alprostadil and pancreatic kininogenas (30 cases for each).The course of treatment was 4 weeks,the nerve conduction and effective rate of 3 groups were compared after treatment.Results Compared with the first group(53.3％),the total effective rate was significantly improved in the second group (80.0％)and the third group(100.0％) (P＜0.05).After treatment,the therapeutic effect of every group was boosted,and the second group was better than the first group,and the last group was best(P＜0.05).Conclusions Alprostadil combined to pancreatic kininogenas is effective and safe for the treatment of elderly diabetic peripheral neuropathy.

Objective To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on sedative efficacy during induction of anesthesia with propofol.Methods Patients,of ASA physical status Ⅰ or Ⅱ,aged 21-69 yr,scheduled for elective thyroid surgery,were randomly divided into 2 groups using a random number table:control group (group C) and TEAS group.TEAS was applied to bilateral Hegu and Neiguan acupoints for 30 min.The frequency was 2/100 Hz,wave length was 0.2-0.6 ms and the intensity was maintained at about 8-12 mA according to the current that could be tolerated.Induction of anesthesia was started at the end of TEAS.Sequential method was used to determine the median effective target plasma concentration (EC50) of propofol causing loss of consciousness in each group.The initial target plasma concentration of propofol was 3 μg/ml.BIS value was recorded every 30 s within 5-8 min after loss of consciousness and the average BIS value was calculated.It was considered to be positive response when the average BIS value was below 50.The target concentration of propofol was decreased/increased by 0.3 μg/ml in the next patient.Results EC50 of propofol causing loss of consciousness was 3.08 μg/ml in group TEAS,and 3.70 μg/ml in group C,and there was significant difference between the two groups.Conclusion TEAS can enhance the sedative efficacy during induction of anesthesia with propofol in the patients.

[Objective] To study the effect of celecoxib on osteoblast apoptosis induced by titanium particle in neonatal rats. [Methods]The best in vitro celecoxib serum concentration for promoting proliferation of osteoblast in neonatal rats was obtained through MTT.One group of rat osteoblast in vitro was cultured with serum containing saline and titanium particle and the other was cultured with serum containing celecoxib and titanium particles.Concentrations of TNF-? and PGE-2 in cells collected after 24 hours were analyzed by ELLSIA,COX-2 mRNA and protein were indicated by FO-PCR and Westren blot.[Results]Some cellar factors such as COX-2,TNF-? and PGE-2 could be induced by titanium particle in in vitro,but celecoxib could inhibit expression of these factors by COX-2 pathway.[Conclusion]Celecoxib coule be a promising drug for treatment of aseptic loosening.

Objective To study the clinical characteristics of obstructive sleep apnea-hypopnea syndrome in the aged. Methods Forty-two over 60 patients with obstruction sleep apnea-hypopnea syndrome (OSAHS) diagnosed by polysomnography (PSG) and 42 matched but less than 60 years OSAHS patients were selected, who were admitted to our hospital from February 2003 to December 2005. The clinical presentations and the results of PSG monitoring were analyzed between the two groups. Results The apnea-hypopnea index (AHI) and microarousal index (MAI) in the aged group were significantly lower than that in the younger group (P0.05). The number of severe OSAHS in the aged group was less than in the younger group (P

Objective To determine the clinical characteristics of post ictal headache (PIH) and clinical risk factors associated with the occurrence of PIH in patients with localization related epilepsy.Methods The subjects were 47 patients with temporal lobe epilepsy (TLE),21 patients with occipital lobe epilepsy (OLE),and 29 patients with frontal lobe epilepsy (FLE).The subjects were directly asked whether headaches occurred just after seizures and its characteristics.Results The characteristics of PIH were:throbbing quality,which was exacerbated by coughing,vomiting,bending,and sudden head movement,accompanied by photophobia,phonophobia,and relieved by sleep.The incidence of PIH was 21 3% for TLE,61 9% for OLE,and 41 4% for FLE.The risk of PIH was significantly higher for OLE than for TLE or FLE,and for patients with generalized tonic clonic seizures.Younger onset age of epilepsy was also a risk factor for PIH.Conclusions PIH possess some characteristics similar to migraine.The occurrence of PIH may be related to the region of epileptic focus and the region of the spread of epileptic discharges.
