Objective:To evaluate the effect of different polishing instruments on the microstructure of composite resin.Methods:Specimens of 5 kinds of resins were randomly divided into three groups and were polished with Astropol(group A),Sof-Lex(group B) and Super-snap(group C)respectively(n=3 for each resin).Specimens of natural enamel surface were used as the controls(group D).The surface roughness(Ra)and microstructure of the specimens were evaluated by an atomic force microscope(AFM).Results:Ra value in group A was lower than that in group B(P=0.015);Z350 XT resin obtained the lowest Ra value among the 5 kinds of resin specimens(P<0.05).All of the resin specimens had similar average Ra after polishing procedure(P>0.05).Conclusion:Astropol polishing instrument is better than Sof-Lex;Z350 XT has better polish performance.The three polishing instruments are ef-fective in polishing the 5 composite resins.

Migraine headache causes significant burdens for both the individual and society.The pathogenesis of migraine is incompletely understood until now.The clinical therapies mainly include medical treatment,surgical treatment,behavior therapy,acupuncture and so on.However,drug treatment could only relieve symptom temporary and bring many side effects for long term use including nausea,vomiting.Surgical therapy maybe becomes an efficient method for migraine headache.The authors have reviewed the pathogenesis of migraine,anatomical basis for surgical therapy and clinical application in this article.

ObjectiveTo investigate the clinical value of ATP bioluminescence tumor chemosensitivity assay (ATP-TCA) for recurrent and refractory non-Hodgkin lymphoma (NHL) specimens in vitro.Methods Thirty-four freshlytaken recurrent andrefractoryNHL specimens weretestedin vitro for cancer chemosensitivity by ATP-TCA.ResultsDrug sensitivity of NHL specimens had heterogeneity.Different drugs had different tumor growth inhibition ratio in vitro.Response rate (RR) of the patients receiving chemotherapy according to in vitro assay was 82.4 % (28/34),complete response rate (CR) was 52.9 % (18/34).In DICE group RR was 60.0 % (18/30),CR rate was 33.3 % (10/30).In GDP group RR was 62.3 % (33/53),CR rate was 26.4 % (14/53).In ATP-TCA group RR was significantly higher than those in DICE and GDP groups (x2 =3.93,P =0.047; x2 =3.98,P =0.046).ConclusionThe results of ATP-TCA assay are correlated well with clinical treatment responses.The assay may be an important and useful method for individual-based chemotherapy of cancers.

OBJECTIVETo observe the efficacy difference of electroacupuncture and auricular acupuncture in the treatment of methamphetamine withdrawal syndrome.
METHODSNinety male patients of methamphetamine addiction were randomized into an electroacupuncture group, an auricular acupuncture group and a control group, 30 cases in each one. In the electroacupuncture group, Neiguan (PC 6), Shenmen (HT 7), Zusanli (ST 36), Sanyinjiao (SP 6), Jiaji (EX-B 2) at T5 and L2 were selected bilaterally. In the auricular acupuncture group, jiaogan (AH(6a)), shenmen (TF4), fei (CO14) and gan (CO12) were selected unilaterally. The treatment was given 3 times a week, totally 12 treatments were required. In the control group, no any intervention was applied. Separately, before treatment and after 1, 2, 3 and 4 weeks treatment, the scores of methamphetamine withdrawal syndrome, Hamilton anxiety scale and Hamilton depression scale were observed in each group.
RESULTSThe total score of methamphetamine withdrawal syndrome, anxiety score and depression score were obviously reduced in 2, 3 and 4 weeks of treatment as compared with those before treatment in the electroacupuncture group and the auricular acupuncture group (all P < 0.05), and showed a trend of gradual decline as the extension of treatment. In 1,2,3,4 weeks of treatment, the total score of withdrawal syndrome, anxiety score and depression score in the electroacupuncture group and auricular acupuncture group were lower significantly than those in the control group (all P < 0.05), in which, the total score of withdrawal syndrome in the electroacupuncture group was lower significantly than that in the auricular acupuncture group in the 4th week of treatment (3.69 +/- 2.446 vs 5.73 +/- 3.169, P < 0.05); the anxiety scores were lower significantly than those in the auricular acupuncture group in 3 and 4 weeks of treatment (8.19 +/- 4.57 vs 9.65 +/- 4.24, 5.27 +/- 2.89 vs 7.38 +/- 3.10, both P < 0.05); the depression scores were lower significantly than those in the auricular acupuncture group in 2, 3 and 4 weeks of treatment (15.35 +/- 5.64 vs 19.81 +/- 5.37, 10.96 +/- 4.52 vs 15.00 +/- 4.53, 7.96 +/- 2.69 vs 12.35 +/- 3.59, all P < 0.05).
CONCLUSIONElectroacupuncture at the body points and auricular acupuncture play the therapeutic role in the treatment of methamphetamine withdrawal syndrome, anxiety and depression. The longer time the treatment is with electroacupuncture at the body points, the more obvious the efficacy will be on the above symptoms.

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.
