Atomoxetine is a noradrenaline transmitter reuptake inhibitor which can selectively inhibit presynaptic noradrenaline transport protein,strengthen noradrenaline's resupination effect,and increases noradrenaline's activity released by synaptic cleft to improve the symptoms of the attention deficit hyperactivity disorder(ADHD)patients.ADHD patients often accompany with other psychological diseases like oppositional defiant disorder,anxiety disorder,which may hinder the diagnosis of ADHD.There is still no accepted effective medicine nowadays.Currently,research on the treatment of the ADHD is more and more popular.Good therapeutic effect of atomoxetine to treat ADHD has been found in resent studies.This article summarized the current management of using atomoxetine to treat ADHD.

Objective To study the effect of three different modes of non-invasive positive pressure ventilation on cardiac indices of premature infants with respiratory distress syndrome (RDS).Method From January 2014 to October 2015,preterm infants who had RDS received intubation-pulmonary surfactantextubation in the neonatal intensive care unit of the Hospital were randomly assigned (by random number table) to three groups based on the primary mode of ventilation:nasal continuous positive airway pressure (NCPAP),bi-level positive airway pressure (BiPAP),and synchronized bi-level positive airway pressure (SBiPAP).The mean airway pressure (MAP) were about 6 cmH2O in the three groups.The level of plasma B-type natriuretic peptide (BNP),cardiac troponin Ⅰ (cTnI),and correct QT intervals dispersion (QTcd) were monitored before and 42-54 h after non-invasive ventilation.Result There were 173 cases in our study,59 of which in NCPAP group,56 in BiPAP group,and 58 in SBiPAP group.The plasma BNP level at 42-54 h after non-invasive ventilation in the three groups were all higher than that before non-invasive ventilation [NCPAP group:(247.9 ± 137.9) ng/L vs.(182.5 ± 1 10.7) ng/L,P =0.007;BiPAP group:(258.5 ± 131.2) ng/L vs.(182.6 ± 105.0) ng/L,P ＜ 0.001;and SBiPAP group:(260.9 ± 159.7) ng/L vs.(177.5 ± 101.5) ng/L,P =0.002].After 42-54 h non-invasive ventilation,there were no significant changes of plasma cTnI level and QTcd in all the three groups (all P ＞ 0.05).The level of plasma BNP,cTnI,and QTcd among the three groups before and after 42-54 h non-invasive ventilation all showed no significant differences statistically (all P ＞ 0.05).Conclusion Longer duration (42-54 h) of non-invasive positive pressure ventilation (MAP:6 cmH2O) in preterm infants with RDS may lead to increased plasma BNP level,and may affect their cardiac function.However,it may not lead to serious myocardial damage and abnormality of ventricular repolarization.There were no significant differences in cardiac indices of premature infant with RDS among NCPAP,BiPAP,and SBiPAP group with the same MAP.

Objective To evaluate the feasibility,technique and preliminary clinical results of the intraoperative three-dimensional (3-D) computer navigation system assisted free vascularized fibular grafting for the treatment of osteonecrosis of the femoral head.Methods From October 2010 to April 2013,14 patients (18 hips) with osteonecrosis of the femoral head were treated by free vascularized fibular graft transfer,assisted by intraoperative3-D computer navigation system.Of 18 hips,8 were classified as stage Ⅱ ;6 as stage Ⅲ,4 as stage Ⅳ according to Steinberg system.The entire procedures were visualized and guided by the 3-D navigation system,including location of optimal entry point,exploration of the field,excision of the necrotic bone tissues,and the fibular grafting transfer with vessel anastomosis.The follow-up records included the results of X-ray,the Harris score of the hip,and the complications.Results Operations of all 14 patients (18 hips) were smooth and successful with patent vessel and umcompromised grafts evidenced by ECT scan at day 7 postoperatively.Postoperative X-ray confirmed the complete eradication of necrotic focuses with surrounding calcified bone and the accurate positioning of fibular grafts.The mean follow-up period was 23.6 months (8-29 months).Harris scores significantly improved from 57.5 ± 14.5 before operations to 87.5 ±2.5 after,with 6 hips' scores classified as Excellent,and 11 as Good.X-ray obtained more than 1 year after operation suggested improvement was achieved in 15 hips.Conclusion Intraoperative 3-D computer navigation system has multiple merits in assisting free vascularized fibular grafting for the treatment of osteonecrosis of the femoral head,including clear anatomic structure,better accuracy,less damage,and reliable functional recovery,which imply it is a highly applicable approach.

Objective To investigate the changes of cardiac function at pre -and post -treatment in preterm infants with patent ductus arteriosus (PDA)in order to guide drug treatment.Methods Totally 84 preterm infants with PDA admitted to Neonatal Intensive Care Unit of Xuzhou Hospital Affiliated to Medical College of Southeast University from July 201 2 to June 201 4 were divided into 4 groups according to treatment drug:Ibuprofen group (27 cases),Indo-methacin group (24 cases),control group (1 1 cases),and Paracetamol group (22 cases).Patients were also divided into symptomatic PDA group (38 cases)and asymptomatic PDA group (46 cases)according to severity;PDA closed group (69 cases)and PDA unclosed group (1 5 cases)according to sequel.The level of plasma brain natriuretic pep-tide (BNP),cardiac troponin I (cTnI),correct QT intervals dispersion (QTcd)were monitored pre -and post -treat-ment.Data were analyzed by using SPSS 1 9.0 software.Results Three cardiac markers at post -treatment were of no significant difference among 4 treatment drugs.The changes of the cTnI and QTcd at pre -and post -treatment were of no significance.The level of BNP in symptomatic PDA group was significantly higher than that in asymptomatic PDA group at pre -treatment [(378 ±94)ng/L vs (1 47 ±75)ng/L,t =2.584,P =0.01 4].In the symptomatic PDA group,the level of BNP at post -treatment [(1 82 ±81 )ng/L]was significantly decreased than that at per -treatment (t =2.741 ,P =0.009).In the asymptomatic PDA group,there was no significant difference between the pre - and post -treatment [(1 21 ±61 )ng/L]in the level of BNP (t =1 .254,P =0.207).There was no significant difference in the level of BNP at per -treatment between PDA closed group and PDA unclosed group [(274 ±91 )ng/L vs (289 ± 87)ng/L,t =-0.874,P =0.391 ].In PDA closed group,the level of BNP at post -treatment [(1 21 ±74)ng/L] was significantly decreased compared with that at per -treatment (t =3.580,P =0.000).In PDA unclosed group, there was no significant difference between the pre - and post -treatment [(245 ±74)ng/L]in the level of BNP (t =0.854,P =0.392).Conclusion Early medication intervention for symptomatic PDA of preterm infants is benefi-cial for the closure of PDA and for attenuating negative effects on cardiac function of PDA.

Objective: To explore the relationship between serum vitamin D level and coronary artery lesion severity and short-term prognosis in coronary artery disease (CAD) patients. Methods: A total of 323 CAD patients diagnosed according to coronary angiogram were selected and the coronary artery lesion severity was evaluated by using Gensini score. Clinical data was collected and serum level of vitamin D and other indicators were determined for statistical analysis. Results: All patients were divided into tertile according to Gensini score. The level of serum vitamin D concentration was significantly different from the lowest tertile to the highest tertile (P=0.000). Serum vitamin D level was negatively correlated with Gensini score in CAD patients (r=-0.182, P=0.001). Multivariate linear analysis showed that vitamin D level was an independent predictor of Gensini score (β=-0.795, P=0.000). There was no difference in the incidence of major advanced cardiovascular events between vitamin D deficiency patients and normal vitamin D level patients (2.05% vs 3.17%, P=0.202) after (18.14±3.04) months' follow-up. Conclusion: There is an independently negative correlation between serum vitamin D and coronary artery lesion severity in CAD patients.

The chemical consitituents from cytotoxic fraction of the Callicarpa nudiflora extract were isolated and purified by a combination of HP-20 macroporous resin, silica gel and Sephadex LH-20 column chromatographies. The structures were elucidated on the basis of the spectroscopic data and comparison of their spectroscopic data with reported data. The cytotoxicity was evaluated by the MTT assay. The 50% and 70% EtOH elutions of EtOH-extract showed significant cytotoxic activities, leading to the isolation of twelve compounds, which were identified as luteoloside(1), lutedin-4'-O-β-D-glucoside(2), 6-hydroxyluteolin-7-O-β-glucoside(3), lutedin-7-O-neohesperidoside(4), rhoifolin (5), luteolin-7, 4'-di-O-glucoside (6), forsythoside B (7), acteoside (8), alyssonoside (9), catalpol(10), nudifloside(11), and leonuride(12). Compounds 3-6, 10 and 12 were isolated from this genus for the first time, and compound 9 was isolated from this plant for the first time. The cytotoxicity assay demonstrated that flavonoids 1-6, in various concentrations, showed monolithic proliferation inhibitory activities against Hela, A549 and MCF-7 cell lines. Compounds 3, 5 and iridoid glycoside 11 possessed higher cytotoxicacivities. In short, flavonoids are the main components of cytotoxic extract from C. nudiflora, while phenylethanoid glycosides are the predominant ingredient but inactive to cancer cell lines. In addition, the minor iridoid glycoside expressed weak cytotoxic activity.

Objective To investigate the therapeutic effect of enteral drip infusion with modified Baitouweng Decoction for the treatment of ulcerative colitis(UC) with damp heat in large intestine at active phase , and to observe its influence on serum levels of inflammatory factors. Methods Sixty patients suffering from mild to moderate UC with damp heat in the large intestine were randomly divided into treatment group and control group, 30 cases in each group. The treatment group was given enteral drip infusion with modified Baitouweng Decoction and the control group was given Mesalazine Enemas enema. The medication lasted for 8 continuous weeks. Before and after treatment, the scores of traditional Chinese medicine (TCM) syndromes and intestinal mucosal signs under enteroscopy, and serum levels of inflammatory factors were observed. Therapeutic effect on single TCM syndrome and clinical safety were also evaluated after treatment. Results After treatment, the scores of each TCM syndrome and intestinal mucosal signs under enteroscopy in the treatment group were much improved (P<0.05 compared with those in the control group); serum interleukin-8 (IL-8) and tumor necrosis factor beta (TNF-β) levels in both groups were decreased, serum IL-10 and IL-13 levels were increased (P <0.05 compared with those before treatment), and the effect in the treatment group was superior to that in the control group (P < 0.05). Except for the abdominal pain, the treatment group had better effect on relieving diarrhea, anal expansion, tenesmus, mucous stool and bloody purulent stool than the control group, the difference being statistically significant (P < 0.05). During the medication, no obvious adverse reaction was found in the treatment group, but 4 cases from the control group had anal burning sensation which had no effect on the mediciation. Conclusion Enteral drip infusion with modified Baitouweng Decoction can inhibit the release of proinflammatory cytokines, reduce the inflammatory response, and promote the healing of intestinal mucosa, which is effective for the treatment of UC with damp heat in large intestine at active phase.

OBJECTIVETo study the effects of aloesin and arbutin on normal cultured human melanocytes in synergetic method.

METHODSBuilding up the system of cultured human melanocytes. The cultured melanocytes in vitro were treated with the mixture of aloesin and arbutin. The cell viability and tyrosinase activity was measured by MTT assay, utilization of L-Dopa as the substrate respectively; melanin content was measured by image analysis system. Furthermore, the effects of the mixture on melanocytes were compared with that of aloesin and arbutin.

RESULTSThe mixture of aloesin and arbutin showed an inhibition on tyrosinase activity of human melanocytes and reduced significantly melanin content. Between the mixture and the single use of aloesin or arbutin, there is significant difference (P < 0.05). On the other hand, the mixture has little influence on melanocytes viability and there is negative significance.

CONCLUSIONThe mixture of aloesin and arbutin can significantly inhibit the tyrosinase activity and melanogenesis of cultured human melanocytes. It showed the effects of aloesin and arbutin in a synergistic manner. It is worth to give farther study later.

OBJECTIVETo study difference in curative effect between intermingled skin transplantation (IT) and microskin grafting (MG) in repairing massive deep burn.

METHODSClinical materials of 101 patients with massive deep burn hospitalized from 1992 to 2008 were retrospectively summarized. Patients were divided into IT group (n = 52) and MG group (n = 49). The size of initial donor site for autologous skin, the wound size initially covered with autologous skin, the survival rate of initial autologous skin grafting, the theoretical expansion multiple of the autologous skin, the actual expansion multiple of the autologous skin, the total size of donated autologous skin, the remained wound condition, and the function of large joint of patients in two groups were compared.

RESULTSIn IT group and MG group, the size of initial donor site for autologous skin was respectively (3.25 +/- 0.48)%TBSA and (3.01 +/- 0.21)%TBSA, the wound size initially covered by autologous skin was respectively (30.4 +/- 3.6)%TBSA and (41.4 +/- 1.3)%TBSA, the survival rate of autologous skin grafting was respectively (99.9 +/- 1.9)% and (87.5 +/- 6.8)%, the theoretical expansion multiple of the autologous skin was respectively 9.5 +/- 1.3 and 13.9 +/- 1.4, the actual expansion multiple of the autologous skin was respectively 9.5 +/- 1.3 and 12.0 +/- 1.5, the difference between two figures of each index was statistically significant (P < 0.05). There was no statistical significant difference between IT and MG group in respect of the total size of donated autologous skin [respectively (14.2 +/- 1.9) and (14.0 +/- 2.1)%TBSA, P > 0.05]. There were 23 patients (44.2%) with residual wounds over 0.5%TBSA in IT group, and 37 cases (75.5%) in MG group. There were 34 patients (65.4%) with good function of large joints in IT group, and 18 cases (36.7%) in MG group.

CONCLUSIONSExpansion multiple of autologous skin after MG is obviously larger than that after IT, thus limited skin source can be fully used. The wound healing quality and the restoration of large joint function of patients treated with IT are better than those of patients treated with MG.
