Objective To evaluate the efficacy and safety of oral ibuprofen for closure of patent ductus arteriosus (PDA) in preterm infants.Methods The related literatures till December 31st,2011 in Cochrane Library,PubMed,EMBASE,Ovid,Springer,China Academic Journal Full-text Database,Wanfang Database,VIP Database and China Biological Medical Literature Database were searched.The inclusion criteria were:(1) the subject of the research was preterm infants with birth weight less than 2500 g and/or gestational age less than 37 weeks; (2) randomized or semirandomized controlled trial; (3) the intervention group received oral ibuprofen,while the control group received oral placebos / intravenous indomethacin or ibuprofen; (4) the main outcome was the failure rate of PDA closure; (5) hemodynamic changes with PDA were detected by ultrasonography.Meta-analysis was performed by Review Manager 4.22 software.Results Eleven randomized controlled trials were included,among which,three were high quality reports.Meta-analysis showed lower failure rate of PDA closure in subjects received oral ibuprofen than in those received placebos orally (RR =0.22,95 ％ CI:0.14-0.35),while the number of infants required operative closure of PDA decreased significantly (RR =0.16,95％ CI:0.03-0.86).Further analysis showed the effect of oral ibuprofen was similar to intravenous indomethacin (RR =0.93,95 ％ CI:0.57-1.53),but better than intravenous ibuprofen (RR=0.42,95％CI:0.26-0.67).However,oral ibuprofen did not reduced the ratio of patients required operation compared with intravenous indomethacin or ibuprofen (RR=0.58,95％CI:0.24-1.41).The incidence of gastrointestinal hemorrhage was higher in oral ibuprofen group than that in placebos(RR=1.99,95％CI:1.13-3.50).The serum level of creatine was lower in oral ibuprofen group than in intravenous indomethacin or ibuprofen group (weighted average=-19.10,95％ CI:-25.12-12.31).Compared with intravenous indomethcin group,less necrotizing enterocolitis cases were identified in oral ibuprofen group,but no statistical significance was found (RR=0.57,95％ CI:0.30-1.09).No long-term outcome was reported in any selected literature.Conclusions Oral ibuprofen for PDA closure in preterm infants appears to be as effective as intravenous or indomethacin,and more effective than intraveous ibuproten.Oral ibuproten represents better safety.

Studies show that heme oxygenase-1 (HO-1) can promote the tumor neovascularization via interacting with angiogenic factors,such as vascular endothelial growth factor (VEGF) and stromal cell-derived factor-1.On the other hand,HO-1 may suppress angiogenesis in tumors via inhibiting the transcription of NF-кB.In a word,HO-1 may participate in the pathophysiological process of tumor angiogenesis,and may be a new target for cancer treatment.

Objective To discuss the laws of treatment of chronic fatigue syndrome(CFS) by acupuncture and moxibustion.Methods The literature between 1998-2008 were searched by means of electronic retrieval.The database was established by Epidata 3.1.Applying Excel 2000 to analyze the literatures on the following aspects:the diagnosis of CFS in TCM,the therapeutic methods and manipulations,acupoint selection,course of treatment and therapeutic effects of CFS treated by acupuncture and moxibustion.Results Of the 78 literatures enrolled,50 diagnozed CFS in TCM as vacuity taxation or vacuity detriment,22 as depression pattern.53 identified disease and administered treatment with settled prescription of acupoints,21 identified patterns and combined points.84 body points and 18 auricular points were founded in the prescriptions involving the points of 14 meridians and extra points.28 were treated with one kind of acupuncture and moxibustion methods,50 with more than one kind of acupuncture and moxibustion methods.48 were acupunctured by means of filiform needle and 8 cooperated with electro-acupuncture,18 by means of moxibustion,18 cupping,9 pricking blood,6 auricular therapy,4 dermal needle,3 point-injection,2 embedding therapy and 2 acupoint application with herbal medicine.44 were treated once a day,21 once every other day.The means of total treatment times were 22?11.52 had the total efficiency above 90%,and 17 between 80%～90%.Conclustion Among all kinds of acupuncture and moxibustion methods in treating CFS,filiform needle,electro-acupuncture,moixbustion and cupping were mostly used,and generally more than one kinds of methods were cooperated.The points selected mainly in UB meridian of foot Taiyang,Ren meridian and Du meridian.The points used in high frequency are as follows:ST36,SP6,UB23,DU20,UB15,UB18,UB20,REN4,REN6 and LIV3,generally it needed comparatively long time of treatment to acquire better therapeutic effects.

OBJECTIVETo summarize and analyze the cone-beam CT (CBCT) imaging features of ameloblastomas for clinical preoperative diagnosis.

METHODSThirty-seven cases with complete data proven by pathology were retrospectively studied for distinct CBCT features.

RESULTSOf the 37 cases, 31 were primary and 6 were recurrent. On CBCT images, the 37 cases were composed of 36 cases (97.3%) of intraosseous lesions (17 cases of multilocular lesions, 17 cases of unilocular lesions, and 2 cases of honeycomb lesion) and 1 case (2.7%) of extraosseous lesion (soft tissue lesion). Of the 17 multilocular cases, 15 (88.2%) showed tongue-shaped crests in lesions. Thirty-four cases (94.4%) showed apparent expansible change toward lip/buccal and (or) palatal/lingual sides ofjaw, with partialcortical erosion.

CONCLUSIONCBCT imaging yields accurate three-dimensional images of lesion shape and structure. Therefore, CBCT can be usedfor the clinical diagnosis and surgical assessment of ameloblastoma.

Objective According to the level of serum cystatin C (Cys-C)in patients with multiple myeloma (MM),to explore its significance of early assessment to renal damage.Methods To select 42 patients with MM(MM group) and 30 healthy subjects(control group),and measure serum Cys-C,creatinine (SCr) and β2-microglobulin (β2-MG).Results The level of serum Cys-C in MM group was significantly higher than that in control group [(2.34 ± 0.57) mg/L vs.(0.66 ± 0.12) mg/L],which increased with ISS stage[Ⅰ,Ⅱ,Ⅲ stage was(1.77 ± 0.38),(2.11 ± 0.46),(3.14-± 1.07) mg/L](P＜ 0.05).Cys-C and β 2-MG,renal function had a positive correlation (r =0.760,0.694,P ＜ 0.05).Conclusion The increasing of Cys-C in MM patients is related to impaired renal function and tumor burden,which can be used as an early assessment indicators.

Objective To establish an accurate method for determining the content of three components in Fufang Buwu Syrup. Methods TLC scanner was selected to detect three components with silica gel G thin layer plate. The sample was separated by using cyclohexane-ethyl acetate-methylenechloride-formic acid (3∶1∶1∶0.2),λS=300 nm. Results The linearity between peak area and ferulic acid was achieved in the range of 0.36-0.84μg, psoralen was achieved in the range of 0.12-0.28 μg, emodin was achieved in the range of 0.01-0.05 μg. The average recovery was 100.7%, 100.8%, 101.0%, and RSD was 1.26%, 1.44%, 1.86%, respectively. Conclusion The method is simple and accurate, which can be used for quality control of Fufang Buwu Syrup.

Objective:To introduce our experience on treatment of melanoma metastasis to lymph nodes by percutaneous radiofrequency ablation combined with microwave coagulation therapy under contrast-enhanced ultrasound guidance and to assess the subsequent clinical efficacy. Methods: The 64 years old male patient with right sole melanoma had an enlarged right inguinal lymph node and received surgical resection twice within 9 months. During the following 2-7 months, more than 20 enlarged lymph nodes appeared along the right iliac artery and right lower limb, complicated with lower limb swelling. Surgical resection was ruled out due to the involvement of the iliac artery and the great number of the enlargements. Chemotherapy and Chinese herb medication were proven to be less effective, then a combined thermotherapy by radio frequency ablation (CelonLab-ENT, Germany) and microwave coagulation (YWY-2T, China) was employed percutaneously under the guidance of contrast-enhanced ultrasound for the treatment. The patient was followed up for 6 months. Results: Intra-and post-operation contrast-enhanced ultrasound scanning and biopsy pathology showed avascularity, necrosis, and atrophy in all the treated lymph nodes, with no obvious complications. The general condition of the patient was good and there was no new lesion found in other sites, except a few ones still receiving ablation in the right lower limb. Conclusion: Percutaneous radiofrequency ablation combined with microwave coagulation therapy under the guidance of contrast-enhanced ultrasound shows a stable killing effect for melanoma metastasis to lymph nodes in this patient, without obvious complications, and should be considered for more clinical applications.

Objective:To prepare poly-L-lactic acid(PLLA)electrospun nanofibers carrying icariin(ICA)(ICA /PLLA)and to evaluate the effects of the ICA /PLLA on MC3T3-E1 cells.Methods:ICA solution was dispersed into PLLA solution,and electrospun fibers were fabricated by W/O emulsion method.The morphology of ICA /PLLA was observed by SEM.The in vitro release kinetics of ICA /PLLA was examined.The attachment of MC3T3-E1 cells on ICA /PLLA was examined by propidiumiodide(PI)labling and ob-served under fluorescent microscope.The proliferation of the cells was measured by MTT assay.The differentiation of the cells was ob-served by alkaline phosphatase (ALP)assay.Results:In vitro,ICA was effectively released from ICA /PLLA for 22 days,cells were attached well on the surface in all groups,ICA did not affect the proliferation of MC3T3-E1 cells(P >0.05),but increased the ALP activity(P <0.05)of the cells.Conclusion:ICA /PLLA can effectively control the release of ICA and promote the differentiation of MC3T3-E1 cells.

Objective To discuss the role of nucleic acid test(NAT)in blood screening to provide the scientific basis for the se-lection of blood screening strategies.Methods The serological detection and NAT were simultaneously performed on 68 662 speci-mens of voluntary blood donation from January 2012 to April 2013;29 samples of HBV DNA positive with serological HBsAg nega-tive were performed the serum HBV markers detection.Partial samples of anti-HIV antibody positive were sent to CDC for conduc-ting the confirmation test.Results Among 68 662 samples,120 cases of single NAT positive were detected out,the residual risk of blood transfusion was 0.175%.In the serum HBV markers detection,the mode of HBcAb was predominant.11 cases of HIV posi-tive were confirmed and all were the NAT positive samples.Conclusion NAT can reduce the residual risk of blood transfusion,en-sure the safety of blood transfusion.NAT and the serological detection are mutual complementation and not replaced by each other. The suitable screening strategy shold be selected.

Objective To explore the application and efficacy of autogenous septal cartilage in the correction of cleft lip nasal deformity.Methods A total of 31 patients with secondary nasal deformity of cleft lip were involved in this study.After autologous nasal cartilage was released,the dislocation of nasal cartilage was corrected,nasal septum cartilage was used as substitute to raise the alar collapse,to reshape the nasal tip cartilage structure and correct the nasal deformity.Results Postoperative incision was primarily healing.For cartilage donor area there was no serious complications,and incision scar was concealed and unobvious; after 6 months to 2 years follow-up,there was no cartilage absorption deformation,the tip of the nose was flat,crack side nosewing collapses,and nasal columella skew was totally corrected,with stable rhinoplasty effects.Conclusions For secondary nasal deformity of cleft lip,the use of nasal septum cartilage to repair nose deformity can not only solve the cartilage source,but also give septal straightening and at the same time the correction effect of external nasal deformity is good.
