Objective To compare the efficiency and safety between Aripiprazole and other traditional drugs for Tourette's syndrome treatment.Methods Databases such as China National Knowledge Infrastructure,Wanfang,VIP,China Biology Medicine Disc,PubMed and Web of Science were electronically searched for studies on Aripiprazole for Tourette's syndrome treatment.According to the inclusion and exclusion criteria,studies,extracted data,and assessed quality were screened.Meta-analysis was performed by using Stata 11.0 software.Results Four studies about Aripiprazole for Tourette's syndrome treatment with 396 patients (Aripiprazole group:201 cases;control group:195 cases) were synthetically and quantitatively analyzed.Meta-analysis results showed that Aripiprazole was better than other traditional agents (placebo,Tiapride,Haloperidol) [standardized mean difference (SMD) =0.21,95％ CI:0.10-0.32].The subgroup by time of treatment analysis results indicated that Aripiprazole was superior to other drugs in 2 weeks (SMD =0.28,95％ CI:0.06-0.50).There was no significant difference in the efficacy between Aripiprazole and other drugs for treatment of Tourette's syndrome in 4 weeks and 8 weeks after treatment (SMD =0.16,0.28;95％ CI:-0.05-0.38、-0.20-0.76).The subgroup by matched drugs results suggested that Aripiprazole was better than Tiapride (SMD =0.29,95 ％ CI:0.15-0.43),but was not significantly different from Haloperidol (SMD =-0.03,95％ CI:-0.28-0.22).There was no significant difference in side effects incidence between Aripiprazole and traditional drugs for treatment of Tourette's syndrome (RR =0.83,95 ％ CI:0.36-1.89).Conclusions Compared with the conventional drugs,Aripiprazole has better therapeutic efficacy in the treatment of Tourette's syndrome in children in 2 weeks.Aripiprazole is better than Tiapride,but equal to Haloperidol in the treatment of Tourette's syndrome.The safety of Aripiprazole needs to be further verified.

Objective To evaluate the efficacy of dexmedetomidine for improvement of postoperative analgesia with sufentanil in pediatric patients with a large area of burn after tangential excision and skin grafting.Methods Forty-two pediatric patients of both sexes with a large area of burn,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,aged 2-10 yr,weighing 13-36 kg,scheduled for elective tangential excision and skin grafting under combined propofol-remifentanil-sevoflurane anesthesia,were randomly divided into 2 groups (n=21 each) using a random number table:sufentanil group (group Suf) and dexmedetomidine plus sufentanil group (group Dex-Suf).The patient-controlled intravenous analgesia (PCIA) was used for postoperative analgesia.PCIA solution contained sufentanil 2 μg/kg and granisetron 100 μg/kg in 100 ml of normal saline in group Suf,and contained dexmedetomidine 2.5 μg/kg,sufentanil 1.5 μg/kg,and granisetron 100 μg/kg in 100 ml of normal saline in group Dex-Suf.The PCA pump was set up with a 0.5 ml bolus dose,a 15 min lockout interval and background infusion at a rate of 2 ml/h after a loading dose of sufentanil 0.1 μg/kg.When Faces Pain Scale score＞2,sufentanil 0.1 μg/kg was injected intravenously as rescue analgesic.The consumption of sufentanil was recorded within 48 h after operation.Ramsay sedation scores at static and dynamic (during dressing changes) conditions were assessed after operation.The parents' satisfaction,requirement for rescue analgesics and incidence of adverse reactions such as agitation,nausea and vomiting were recorded after operation.Results Compared with group Suf,Ramsay sedation scores at static and dynamic conditions and patients' satisfaction scores were significantly increased,and the consumption of sufentanil,requirement for rescue analgesics and incidence of agitation,nausea and vomiting were significantly decreased after operation in group Dex-Suf (P＜0.05).Conclusion Dexmedetomidine significantly improves postoperative intravenous analgesia with sufentanil in the pediatric patients with a large area of burn after tangential excision and skin grafting,and combination of dexmedetomidine and sufentanil is recommended for this type of pediatric patients.

Objective To evaluate the practicability of using flow cytometry analysis for diagnosis of non-hodgkin′s lymphoma ( NHL) among children with serous effusion.Methods Twelve children who were diagnosed with malignant lymphoma from February 2011 to November 2013 at Shanghai Children′s hos-pital were recruited in this study.Pleural effusion and ascites samples were collected from those children who showed serous effusion as initial symptoms and analyzed by using flow cytometry based immunophenotyping. The antibodies used for immunophenotyping included CD45, CD10, CD33, CD7, CD1a, MPO, cCD3, CD79a, CD22, CD19, CD20, CD5, CD3,κ,λ,αβ,γδ,CD56 and other common markers for T, B and NK cells.Anti-CD30 antibody was used when necessary.Results All of the twelve cases with serous effusion were diagnosed with aggressive NHL.Six out of the twelve children including five cases with ascites and one case with pleural effusion showed high expression of CD20 and were classified as NHL-B type by flow cytom-etry.Three children with pleural effusion and one child with both pleural effusion and ascites were typed as NHL-T as characterized by monoclonal expression of αβorγδ.The other two children with pleural effusion were diagnosed with anaplastic large cell lymphoma with positive expression of CD30 and morphological het-erogeneity.Conclusion Flow cytometry analysis based immunophenotyping could be used as an auxiliary method for rapid and accurate diagnosis of lymphoma in children with serous effusions.

Aim To investigate the effect of indirubin derivative PHⅡ-7 and TRAIL on proliferation in breast cancer cell MCF-7 and its MDR counterpart MCF-7/ADR and the mechanism.Methods Growth inhibition rate was examined respectively by MTT assay under treatment with TRAIL or PHⅡ-7 or in combination. Cell apoptosis and ROS production were examined by flow cytometry.The change of TRAIL receptors(DR4/DR5 )in mRNA was analysed by realtime PCR.Re-sults IC50 of PHⅡ-7 on MCF-7 and MCF-7/ADR was (4.49 ±1.55 ),(3.44 ±0.90 )μmol · L-1 respec-tively;MDA-MB-231 was TRAIL sensitive cell line, and apparently TRAIL induced apoptosis in MDA-MB-23 1 .Low concentration of PHⅡ-7 in combination with TRAIL could augment TRAIL-induced cytotoxic effect including apoptosis while TRAIL or PHⅡ-7 treatment alone had limited cytotoxity to those cells.Besides, PHⅡ-7 at this concentration had little toxicity to hu-man peripheral blood mononuclear cells even if in com-bination with TRAIL.PHⅡ-7 generated ROS produc-tion inside MCF-7 and MCF-7/ADR cells and up-regu-lated DR4/DR5 expression concentration dependently. Once upon ROS scavenger NAC involved,the effect of TRAIL receptors up-regualtion by expression was abro-gated.Conclusions PHⅡ-7 at low concentration could improve the sensitivities of breast cancer cell MCF-7 and MCF-7/ADR to TRAIL,the mechanism of which may be the ability of ROS production by PHⅡ-7 help up-regulated TRAIL receptor DR4,DR5 .Our re-search set a solid foundation for PHⅡ-7 in combination with TRAIL in future clinical application.
