BACKGROUND: The etiology and pathogenesis of Tourette syndrome(TS)is still unacknowledged, and related studies on the relationship between TS and hypoironemia are unavailable. Since hypoironemia has been found existed in children with TS who showed better outcomes after receiving adjuvant ferralium, thereby this study was designed to investigate the relationship between TS and serum iron.OBJECTIVE: To study the relationship between TS and serum iron.SETTING: At a nursing science department of a university-affiliated hospital, pediatric department of a university affiliated hospital and sectional hospital.PARTICIPANTS: Between June 1997 and December 2000, 45 children with TS received treatment at pediatric clinic of Chenghai sectional people' s hospital, Shantou city, who accorded with the diagnostic standards of the second edition of Chinese Psychopathy Category and Diagnostic Standards,those who were confirmed as brain organic diseases by CT and MIR were excluded.METHODS: Serum iron, hemoglobin and the number of red blood cells were determined in 45 TS children and compared with that in 38 controls.MAIN OUTCOME MEASURES: Difference of the level of serum iron and the incidence of hypoironemia between two groups.RESULTS: The level of serum iron was(12.79 ±0.67) μmol/L in experimental group, obviously lower than(19.26 ± 5.38) μmol/L in control.group( P ＜ 0. 005), the incidence of hypoironemia was 42% significantly higher than13% of control group( P ＜ 0. 005).CONCLUSION: Quite a lot of children with TS have hypoironemia that might be one of the pathogenesis factors, the possible mechanism is, as the result of hypoironemia, decreased activity of monoamine oxidase led to abnormal monoamine neurotransmitter.

Objective Inquire into the function and mechanisms of Sanye Insect tea of lowering the blood pressure. Method The rat model of renal hypertension was replicated by aqueezing two kidneys (2K1C-RHR) to observe the blood pressure-lowering process of Sanye Insect tea on the change of the content of CGRP, analysis the change with the relation of the AngⅡ level, and compare with Liuwei Dihuang and Captopril Tablets. Result The blood pressure value of renal hypertension rats obviously increased, the blood plasma CGRP lowered and the level of AngⅡ increased. High and low dosages of Sanye Insect tea had this improvement of different degree. Conclusion Sanye Insect tea has the effect of lowering the blood pressure of 2K1C-RHR. Incressing the content of CGRP and regulating the level of Ang Ⅱ to make blood vessel extend is one of the function mechanism of Sanye Insect tea.

Objective Dickkopf-1 (DKK-1) is an antagonist of the Wnt signaling pathway of bone formation and it is the target gene of TNF.When DKK-1 is inhibited,osteoprotegerin (OPG) would increase,OPG can antagonize bone erosion caused by receptor activator of NF-κB ligand (RANKL).Detection the levelsof serum DKK-1,OPG,RANKL and TNF-α of patients with AS before and after applying TNF-α antagonist,the effects of anti-TNF-α treatment on signaling pathway of bone formation was explored.Methods Medical records and serum samples of 43 AS patients receiving TNF-α receptor-Ⅱ IgG Fc fusion protein for 12 weeks were collected and the levels of serum DKK-1,OPG,RANKL and TNF-α were detected by enzyme-linked immunosorbent assay.Paired t-test and Person's correlation analysis were used for data analysis.Results Disease activity indexes in AS patients with anti-TNF-α treatment,including VAS score,time of morning stiffness,BASDAI,BASFI,ESR and CRP,which were [(2.7±2.0) cm,(7±4) min,1.1±1.1,0.8±1.2,(10±9) mm/1 h and (16±26) mg/L] respectively,were reduced when compared with those before treatment,[(7.6±1.9) cm,(46±33) min,6.0±1.3,4.4±2.0,(39±29) mm/1 h and (76±43) mg/L] respectively,and the differences were statistically significant (P＜0.05).Serum levels of DKK-1,(3.3±1.5) μg/L vs (3.2±1.3) μg/L,OPG,(144±71) pg/ml vs (136±62) pg/ml,and RANKL,(71±37) pg/ml vs (68±30) pg/ml,were not changed (t=14.043,8.031,20.166,13.521,7.679,9.563,all P＞0.05).The levels of TNF-α increased from (1.9±1.3) pg/ml to (55.0±50.6) pg/ml (t=6.951,P＜0.05).There were no relations between DKK-1 and TNF-α,RANKUOPG,patient VAS,duration of morning stiffness,BASDAI,BASFI,ESR and CRP,allP＞0.05.Conclusion Clinical indicators are improved significantly by anti-TNF-α therapy; however,it should not be withdrawal suddenly.There is no relationship between serum levels of DKK-1 and level of inflammation in AS patients.

Objective:To investigate the remodeling of alveolar bone and the changes of roots after an-terior retraction with maximum anchorage by analyzing CBCT data from adult cases.Methods:The sam-ple comprised 48 incisors and 24 canines from 12 patients (18 to 40 years of age)with problems of ma-xillary protrusion or upper arch protrusion.CBCT scans were exposed before and after treatment,and la-teral cephalometric images as well as multiple planar reconstruction images were reconstructed.Tracing superimpositions of sagittal sections and three-dimensional reconstructions were done for qualitative analy-sis.For all maxillary anterior teeth,changes of root length,alveolar bone height and labial-palatal thick-nesses at different levels were evaluated.The average of measurements taken by the same tester in three times was processed by SPSS 17.0 statistical package.Results:In 6 of the 12 cases,alveolar thickness became thinner on labial side [apical area:(-0.64 ±1.18)mm]while thicker on palatal side [apical area:(0.93 ±2.0)mm]and the root length decreased[(-0.95 ±0.79)mm].In the other 6 cases, the incisors’alveolar bone became thicker on labial side [apical area:(2.12 ±1.46)mm]while thin-ner on palatal side [apical area:(-2.88 ±0.58)mm]and the loss of root length was obvious[(-2.12 ± 1.43)mm].In all the 12 cases,the canines’alveolar bone became thinner on labial side especially on the apical level [(-0.27 ±1.86)mm]while greatly thicker on palatal side [apical area:(6.40 ± 6.00)mm]and the root resorption was slight [(-1.12 ±1.19)mm].For all the anterior teeth,the height of alveolar bone reduced around them after retraction.Conclusion:When the root apical moved more palatally,more root resorption would occur and the alveolar bone would get thicker on labial side but thinner on palatal side and thinner as a whole after anterior retraction with maximum anchorage.In the vertical direction,the height of the alveolar bone generally decreased on all sides and decreased the most on the palatal side.

ObjectiveTo observe the effect of acupoints stimulation with silver spike point therapy on insomnia.Methods60 patients with insomnia were randomly divided into the trial group and control group with 30 cases in each group. Patients of the trial group were treated by acupoints stimulation with silver spike point therapy and patients of control group were treated only with Clonopin. All patients of two groups were tested with Self-Rating Scale of Sleep (SRSS) before and after treatment.ResultsThe curative effect rate of the trial group was 86.6%; that of the control group was 60%; the curative effect of the trial group was superior to the control group (P<0.05). SRSS difference of the trial group pre-and post-treatment was 12.79±3.20; that of the control group was 10.1±3.89. There was also a significant difference between two groups (P<0.01).ConclusionThe silver spike point therapy has the better curative effect on insomnia than Clonopin.
