Fragile X syndrome (FXS) is one of the most common causes of mental retardation, but modern medicine has not yet produced a good therapeutic effect. Clinical practice and scientific studies have showed that acupuncture has a marked therapeutic effect on mental retardation, but researches on the mechanism of its action are still not mature. In view of this, this article will focus on the present situation of FXS study and expound the feasibility of NLGN-3 protein as a target for the mechanism of action of acupuncture on FXS.

OBJECTIVETo compare the difference of clinical efficacy on sleeping disorder in the children with encephalopathy between the combined therapy of acupuncture at head points and seed-pressure at ear points and the simple acupuncture at head points.

METHODSThirty cases of sleeping disorder induced by encephalopathy werei randomized into an observation group and a control group, 15 cases in each one. In the observation group, the combined therapy of acupuncture at head points and seed-pressure at ear points was adopted. The head points in cluded Sishencong (EX-HN 1), Shenting (GV 24) and Benshen (GB 13). The ear points were the positive reactive sites in the cymba and cavum conchae. In the control group, acupuncture was applied simply to the acupoints on the head. The treatment was given once on every Tuesday and Friday a week separately, 30 min each time. Totally, 16 treatments were required. Children's sleeping habit questionnaire (CSHQ) was used to observe the sleep improvements and the efficacy in the patients of the two groups.

RESULTSIn the observation group, the results of sleep resistance, sleep anxiety, night sleep wake, parasomnias, sleep dyspnea, daytime somnolence and the total score after treatment were all improved apparently as compared with those before treatment (all P<0. 05). In the control group, the results of night sleep wake, parasomnias, daytime somnolence and the total score after treatment were improved apparently than those before treatment (all P<0. 05). In the observation group, the results of sleep resistance, sleep dyspnea and the total score after treatment were better than those in the control group (all P<0. 05) and the scores of sleep anxiety and daytime somnolence in the control group were better than those in the observation group after treatment (both P<0. 05).

CONCLUSIONThe combined therapy of acupuncture at head points and seed-pressure at the positive reactive sites in the cymba and cavum conchae achieves the superior efficacy on sleep resistance and sleep dyspnea as compared with the simple acupuncture. The efficacy of simple acupuncture is more satisfactory on sleep anxiety and daytime somnolence.

Objective　To investigate the prognosis in risk of ventricular arrhythmia in coronary heart disease with heart rate variability (H RV), left ventricular ejection fraction (LVEF) and other clinical background dat a. Methods　A total of 81 patients were divided into ventricular premature beats (VPBs)≥30/h group and VPBs<30/h group. Their LVEF, HRV and cli nical data were studied and analyzed. Results　The age and blood pressure between 2 groups had no significant difference. LVEF, standard deviati on of all normal RR intervals (SDNN), SD of the average of NN interval (SDANN) a nd HRV triangular index (HRVI) were significant less in VPBs≥30/h group than in VPBs<30/h group (43.29±15.38 vs 67.33±11.47，P＜0.01；90.05±22.2 9 vs 117.90±30.32，P＜0.05；77.43±17.78 vs 105.69±28.79，P＜0.05 ；24.54±8.70 vs 32.70±10.87，P＜0.05, respectively). Incidence of myo cardial infarction (MI) was larger in VPBs≥30/h group than VPBs<30/h group. LVE F was the independent predictable factor in risk of ventricular arrhythmia with multinomial regression logistic analysis（B=0.119, P=0.032）. Co nclusion 　Our findings indicate that LVEF is an independent predictable factor i n risk of ventricular arrhythmia in coronary heart disease. Although HRV and MI history can not be used to predict VPB, significant difference is found between 2 groups. High-risk patients could be selected successfully when these data are considered in combination.

Objective: To research the functional segments of B-FA molecule binding invariant chain and their characters. Methods:The DNA segments (α1α2, sα1α2 and α3TC ) of B-FA genes were respectively cloned and inserted into prokaryotic or eukaryotic expression plasmids,then they were singly or co-transfected with Ii gene into the engineering bacteria E. coli (BL-21)or 293T cells. After induction of expression,affinity chromatography and SDS-PAGE identification,the binding between B-FA segments and Ii molecule and co-localization in cells were observed with Pull-down and Western blot. Results:First three recombinant prokaryotic expression plasmids and four recombinant eukaryotic expression plasmids were constructed. The single molecules expressed by B-FA segments were observed after an affinity chromatography. Secondly the complexes of Ii/B-FA-α1α2 and Ii/B-FA-sα1α2 were detected by a Pull-down from the co-transfected corresponding prokaryotic expression plasmids,but no complex of Ii andα3TC,also in the western blot it was detected that B-FA-α1α2 or B-FA-sα1α2 as functional segment could bind Ii to form complex. Finally in eukaryotic expression 293T cells B-FA-sα1α2 kept localization, the same as B-FA. Conclusion: Chicken B-FA-α1α2 is function segment to bind with Ii molecule and keeps the location characters same as B-FA. The results of this research first time provide experimental evidence about B-FA functional region binding segment to Ii molecule.
