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.

Objective To assess longitudinal segmental myocardial strain and displacement of left ventricle (LV) in patients with dual chamber pacing (DDD) using velocity vector imaging (VVI) and to explore the clinical application value of VVI in assessing left ventricular motion.Methods A total of 23 patients before and after DDD pacemaker implantation were enrolled in this study.The peak systolic strain and displacement of ventricular segments were measured with VVI and compared before and after pacemaker implantation.Results Compared to the values at the baseline,the strain and displacement of lateral,interventricular septum,anterior and posterior wall of LV in patients with pacing were significantly decreased.The strain,displacement of basal and mid segments with pacing were decreased as well(P＜0.01).The left ventricular strain and displacement in patients with pacing were significantly decreased than those of patients at the baseline(P＜0.05).Left ventricular longitudinal displacement before and after DDD pacing was significantly decreased from basal,mid to apical segments.But no significant difference was found in longitudinal strain from basal,mid to apical segments of LV.Conclusions (1) Left ventricular strain and displacement in patients with pacing were different between those before and after DDD pacing.(2) VVI can accurately assess left ventricular strain and displacement in patients with DDD pacing,and can become a powerful mean to assess the regional myocardial function.

Background The aspheric intraocular lenses(IOLs)can reduce ocular spherical aberration to some degree.However,the clinical effect depends more on the IOL proper alignment.It becomes more important to study the IOL position in eye,Objective This study was to analyze the position alteration of IOL after phacoemulsification combined with implantation of one-piece soft IOLs.Methods In this prospective control study,80 eyes of 40 patients with age-related cataract were enrolled.The phacoemulsification with IOL implantation was performed in all the eyes.Decentration and tilt of IOL in the nasal superior,superior temporal,inferior temporal and nasal inferior quadrants(the intersection point of the system optical axis and the IOL maximum cross plane were regarded as the ordinate origin)were measured by rotating Scheimpflug camera(Pentacam Oculus)in 3 months postoperatively under the mydriasis condition.Written informed consent was obtained from each subject prior to this trial.Results In the right eye group,the IOL decentered toward temporal in 26 eyes(65％)and infratemporal in 16 eyes(40％).IOLs tilted temporally in the horizontal plane in 37 eyes(92.5％)and tilted inferiorly in the vertical plane in 34 eyes(85.0％).In the left eye group,IOLs decentered temporally 33 eyes(82.5％)and 20 IOLs (50％)infratemporally,IOLs tilted temporally in the horizontal plane in 37 eye(92.5％)and 36 IOLs(90％)tilted inferiorly in the vertical plane.There was no statistical difference for the intercomparsion of horizontal/vertical decentration in various quadrant in the right eye(F =0.221,0.792,P＞0.05).The obvious elevated horizontal decentration was found in the supertemporal and infratemporal quadrants compared with supernasal quadrant in the left eyes but there was no significant difference in the vertical decentration among 3 quadrants(F=0.576,P＞0.05).Decentrations were positively correlated with the tilt in both horizontal and vertical plane(right eye horizontal plane:r=0.374,P=0.002;right eye vertical plane:r=0.402,P=0.001 ;left eye horizontal plane:r=0.377,P=0.002；left eye vertical plane:r=0.347,P=0.002).Conclusions The one-piece soft IOLs(Adapt AO)decenter toward temporal mostly in 3 months after surgery,especially infratemporally in the eye.And the optical axis of the IOL tilt toward infratemperol mostly in both right and left eyes.The decentration and tilt are consisted in the corresponding direction between the right and left eyes.The position of the IOLs showed mirror symmetry between right and left eyes.The IOLs decentration show the positively correlation to tilt whatever in horizontal and vertical plane.
