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.

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 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.

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 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 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 evaluate the role of μ-opioid receptor (MOR) in attenuation of bone cancer pain by anti-nerve growth factor (anti-NGF) in rats. Methods Part Ⅰ Sixty female SD rats weighing 200-220 g were randomly divided into 4 groups (n = 15 each): sham operation group (group S), sham operation + anti-NGF group (group SN), bone cancer pain group (group P) and bone cancer pain+ anti-NGF group (group PN) . Bonecancer was induced by intra-tibial inoculation of 1 × 105 Walker 256 breast cancer cells in group P and PN. Group S and SN received injection of PBS 10 μl. APE 10 catheter was inserted at L2,3 interspace into the epidural space 13 days after cancer cell inoculation. Three days after the catheter was successfully placed, group SN and PN received intrachecal (IT) injection of anti-NGF 10 μg (in normal saline (NS) 10 μl) and group S and P IT injection of NS 10 μl twice a day for 5 consecutive days. The number of spontaneous flinches (NSF), paw withdrawal latency (PWL) and paw withdrawal threshold (PWT) were measured before and 13, 16, 18, 21 day after cancer cell inoculation. The animals were sacrificed at 21 day after cancer cell inoculation and the spinal cord dorsal horn and dorsal root ganglion were removed for determination of MOR and MOR mRNA expression. Part Ⅱ Thirty female SD rats weighing 200-220 g were randomly divided into 2 groups (n = 15 each): bone cancer pain + anti-NGF group (group PN) and bone cancer pain + naloxone + anti-NGF group (group PNN). Bone cancer was induced by intratibial inoculation of 1 × 105 Walker 256 breast cancer cells. APE 10 catheter was inserted at L2-3 interspace into the epidural space 13 days after cancer cell inoculation. Three days after the catheter was successfully placed,group PN received IT injection of anti-NGF 10 μg (in NS 10 μl) and group PNN IT injection of naloxone 10μg (in NS 25 μl) and 0.5 h later IT injection of anti-NGF 10 μg (in NS 25μl) twice a day for 5 consecutive days. NSF,PWL and PWT were measured before and 13, 16, 18, 21 days after cancer cell inoculation. Results Part ⅠCompared with group S, no significant change was found in NSF, PWL and PWT in group SN, and in MOR and MOR mRNA expression in group SN and PN (P ＞ 0.05), NSF was significantly increased, PWL shortened, PWT decreased at 13-21 days after inoculation in group P and PN, and MOR and MOR mRNA expression was down-regulated in group P (P ＜ 0.05 or 0.01). Compared with group P, NSF was significantly decreased, PWL prolonged, PWT increased, MOR and MOR mRNA expression was up-regulated in group PN at 18-21 days after inoculation (P ＜ 0.05 or 0.01). Part Ⅱ Compared with group PN, NSF was significantly increased, PWL shortened, PWT decreased at 18-21 days after inoculation in group PNN (P ＜ 0.05 or 0. 01). Conclusion The mechanism by which anti-NGF attenuates bone cancer pain in rats is related to the activation of MOR.

In recent years, the research hot in the field of solid tumor and blood tumor focuses on the myeloid-derived suppressor cells (MDSCs).In tumors, MDSCs not only exert immunosuppression by inhibiting T cell proliferation, destroying the functions of natural killer cells and recruiting regulatory T cells, but also play non-immunosuppression roles in the promotion of angiogenesis and tumor metastasis.All of these hinder the anti-tumor therapy, and particularly affect the curative effect, which are related with a poor clinical prognosis.MDSCs can be used as prognostic markers, which provide new targets for immunotherapy.

OBJECTIVE:To investigate the effect and cost of Multidimensional iron oral liquid and Polysaccharide iron com-plex capsules in the treatment of iron deficiency anemia during pregnancy. METHODS:By retrospective study,80 cases of iron de-ficiency anemia during pregnancy were divided into control group and trial group in accordance to different therapy plans,with 40 cases in each group. Control group was given Multidimensional iron oral liquid orally,10 ml each time,bid,after breakfast and supper,for consecutive 4 weeks;trial group was given Polysaccharide iron complex capsules orally,0.30 g each time,qd,for con-secutive 4 weeks. Clinical efficacy,erythrocyte related lab indexes,satisfactory rate and ADR were compared between 2 groups, and cost-effectiveness analysis was adopted for economic evaluation. RESULTS:The total effective rate of experimental group was 95.0%,which was higher than 85.0% of control group,but without statistical significance(P>0.05);hemoglobin level,erythro-cyte count and average volume of erythrocyte of trial group were significantly higher or more than control group,and satisfactory rate(95.0% vs. 65.0%)were significantly higher than control group,with statistical significance(P<0.05);no obvious ADR was found in 2 groups. Total cost of trial group and control group were 243.60 and 166.32 yuan,and cost-effective ratio was 2.56 and 1.96;incremental cost-effective ratio was 7.73. Results of sensitivity analysis were same to the result. CONCLUSIONS:Both Multi-dimensional iron oral liquid and Polysaccharide iron complex capsules can improve anemia in patients with iron deficiency anemia during pregnancy. Polysaccharide iron complex capsules show better therapeutic efficacy and satisfactory rate,but it is relatively ex-pensive. Drugs should be selected according to economic situation.
