Atomoxetine as a nonstimulant medicine was approved by the Chinese Food an Drug Administration and provide a new selection of treatment drugs for attention deficit hyperactivity disorder (ADHD). Tomoxetine is a noradrenaline transmitter reuptake inhibitor which can selectively inhibit synapsis noradrenaline transport protein, strengthen noradrenaline's resupination effect, and increase noradrenaline's activity released by synaptic cleft to improve the symptoms of the ADHD patients. Compared with methylphenidate, atomoxetine does not affect the concentration of the neurotransmitter dopamine and does not induce or increase the Tourettes' syndrome, therefore atomoxetine is more suitable to treat ADHD together with Tourettes syndrome. In this article the treatment of atomoxetine for ADHD, including the indications, dosage as well as adverse reactions and efficacy assessment are reviewed.

Objective To investigate the effects of cystectasia with sodium hyaluronate solution on ketamine related cystitis.Methods From June 2008 to October 2012,29 patients with ketamine related cystitis were analyzed,among which 27 were males and 2 were females.Their age ranged from 18 to 36 years old with a mean age of 25.All of them had frequency,urgency,urodynia and suprapubic pain.Voiding volume ranged from 10 to 160 ml and the interval duration ranged from 10 to 60 min.The test of ketamine in urine was positive.Patients were divided into four groups according to the treatment modality,namely the surgical treatment group (group A,n =11),surgery followed by addiction relapse group (group B,n =7),drug treatment group (group C,n =6) and non-drug treatment group (group D,n =5).Patients in group A and B underwent cystectasia with sodium hyaluronate solution under combined spinal-epidural anesthesia,and patients in group B were reported of addiction relapse within 2 weeks after cystectasia treatment.Patients in group C were free of the addiction to ketamine,while those in group D still rely on the ketamine.The average urine volume,OABSS and PUF scores were recorded 2 weeks and 4 weeks after the treatment.Results Two weeks after cystectasia,the average urine volums in group A and B were (107.7±39.6) ml and (95.0±35.5) ml respectively,which was larger than that in group D (42.0±13.5) ml,plus the volume in group A was larger than that in group C (63.3± 16.3) ml.The aforementioned differences were considered statistically significant (P＜0.05).As for OABSS and PUF scores,scores in group A [(6.0±2.6),(14.8± 4.2)] were lower than those in group C [(9.5±2.4),(22.5±2.2)].Furthermore,scores in group B [(9.0±2.4),(19.57±2.7)] were lower than those in group D [(12.2±1.9),(26.4±3.5)] (P＜0.05).Four weeks later,the average urine volume,OABSS and PUF scores in group A [(106.4±37.5) ml,(5.6± 2.5),(13.5±4.0)] and group C[(113.3±27.3) ml,(6.3±2.2),(14.5±2.7)] were significantly different from those in group B [(52.1±21.6) ml,(11.1±1.3),(26.4±2.8)] and group D [(40.0±13.7)ml,(12.0±1.6),(26.6±3.6)] (P＜0.05).While,no obvious distinction was observed between group A and group C,group B and group D in terms of average urine volume,OABSS and PUF scores at 4 weeks postoperatively (P＞0.05).Conclusions Cystectasia can efficiently alleviate lower urinary tract syndromes in patients with ketamine related cystitis.

Objective: To systematically evaluate the factors affecting diabetic retinopathy (DR) among Chinese adult patients with type 2 diabetes mellitus (T2DM), so as to provide insights into establishment of personalized risk prediction models for DR. Methods: Case-control studies pertaining to factors affecting DR among Chinese adults were retrieved from international and national databases, including CNKI, Wanfang Data, SinoMed, PubMed, Web of Science, Embase and CINAHL from inception to March 31, 2023. A meta-analysis was performed using the software Stata 17.0, and subgroup analysis was performed to explore the source of heterogeneity. Sensitivity analysis was performed using the leave-one-out method, and the publication bias was evaluated using the Egger's test and trim-and-fill method. Results: Totally 4 969 publications were retrieved, and 35 case-control studies were finally enrolled, including 32 high-quality publications (91.43%). The included studies involved 29 228 participants and 10 568 DR patients, and the prevalence of DR was 36.16%. Meta-analysis revealed that age (OR=1.06, 95%CI: 1.00-1.13), duration of T2DM (OR=1.09, 95%CI: 1.08-1.11), systolic blood pressure (OR=1.02, 95%CI: 1.01-1.03), glycated hemoglobin A1c (OR=1.38, 95%CI: 1.26-1.50), fasting blood glucose (OR=1.57, 95%CI: 1.07-2.31), urinary albumin to creatinine ratio (OR=1.50, 95%CI: 1.10-2.04), serum uric acid (OR=1.01, 95%CI: 1.00-1.01), urine microprotein (OR=2.01, 95%CI: 1.96-2.07), triglyceride (OR=1.77, 95%CI: 1.42-2.21), and total cholesterol (OR=1.82, 95%CI: 1.50-2.21) were risk factors for DR, and glomerular filtration rate (OR=0.98, 95%CI: 0.97-0.98) and C-peptide (OR=0.79, 95%CI: 0.68-0.93) were protective factors for DR. Sensitivity analysis of age effects was not robust. Following adjustment for glomerular filtration rate with the trim-and-fill method, there was still a publication bias, and the publication bias of other influencing factors had no impact on pooled effects. Conclusions Age, course of T2DM, systolic blood pressure, glycated hemoglobin A1c, fasting blood glucose, urinary albumin to creatinine ratio, serum uric acid, urine microprotein, triglyceride and total cholesterol were risk factors, and glomerular filtration rate and C-peptide were protective factors for DR among Chinese adults.

AlM:To discuss the protective effect ofα-mangostin on retinal light damage in mice.METHODS:Totally 30 Balb/c mice, aged 6~8wk, were randomly divided into the control group, light-exposure group and α-mangostin group. Every group contained 10 mice. Mice of α-mangostin group were treated with alpha-mangostin at the dose of 30mg/( kg · d ) body weight by intragastric administration daily for 7d, and then exposed to white light at the 5th d. The light-exposure group and α-mangostin group were exposed to 5 000 ± 200lx white light-emmiting diodes (LEDs) for continuously 1h to establish the mice model of retinal light damage. Flash -electroretinograme was recorded 72h after light exposure. The changes in retinal morphology of mice were observed by light microscopy. Retinas were extracted to detect the malondialdhyde ( MDA ) content change of the retinal homogenate.RESULTS: Flash-electroretinogram ( F-ERG ) showed that retinal dysfunction was less severe in α-mangostin group than in light-exposure group ( P<0. 05 ). Light microscopy test showed that retina structural damage was less severe in α-mangostin group than in light-exposure group (P<0. 05). The level of MDA in retinal tissue of α-mangostin group was significantly lower when compared with light-exposure group (P<0. 05).CONCLUSlON: α-mangostin inhibits lipid peroxidation induced by light damage and protect retina against light damage.

OBJECTIVETo test the different contrctile responses of extracellular nucleotides, such as ATP, UTP and nucleotide uridine adenosine tetraphosphate (Up4A) in gastric longitudinal muscle (LM) and circular muscle (CM). Examined the effect of P2X and P2Y receptor antagonists (in this study, we used IP5I and suramin) and cyclooxygenase inhibitor (indomethacin) on Up4A induced contractile responses in LM and CM.

METHODSThe rats were sacrificed and the stomachs were opened to gain LM and CM. Using organ bath system to assess contrctile responses of smooth muscle.

RESULTSUp4A could induce contractile responses in both CM and LM, which were similar with ATP and UTP. IP5 did not attenuate Up4A could induce contractions in both LM and CM, but suramin and indomethacin significantly inhibited Up4A contraction in CM, but not in LM.

CONCLUSIONOur results suggest that extracellular nucleosides and their inhibitors induce different responses between LM and CM.
