OBJECTIVETo compare the differences in the efficacy on lower limb motor function in children with spastic cerebral palsy between the combined therapeutic program of Jin three-needle therapy and MOTOmed intelligent motor training and the simple MOTOmed.

METHODSEighty children with spastic cerebral palsy were randomized into an observation group and a control group, 40 cases in each group. In the observation group, Jin three-needle therapy was used at four mind points, three brain points, three intelligent points, three temporal points, three knee points and three foot points, as well as Chengjin (BL 56), Chengshen (BL 57) and the other. Additionally, MOTOmed was given in assistance with conventional rehabilitation training. In the control group, MOTOmed and the conventional rehabilitation training were adopted. In the two groups, the treatment was given once a day, 20 treatments made one session and there were 3 to 5 days at interval between the two sessions. The efficacy evaluation was performed after continuous 3 sessions of treatment. The gross motor function measure (GMFM) and modified Ashworth scale (MAS) were applied for the evaluation before and after treatment in the two groups.

RESULTSAfter 3 sessions of treatment, GMFM score was increased apparently as compared with that before treatment in the two groups (P < 0.01, P < 0.05). After treatment, GMFM score in the observation group was increased more remarkably than that in the control group (55.32 +/- 17.10 vs 47.48 +/- 17.18, P < 0.05). After treatment, the total effective rate of gastrocnemius Ashworth spasm grade [90.0% (36/40)] in the observation group was better apparently than [72.5% (29/40)] in the control group (P < 0.05).

CONCLUSIONThe combined therapeutic program of Jin three-needle therapy and MOTOmet intelligent motor training improves the lower limb motor function of the children with spastic cerebral palsy and its efficacy is better than simple MOTOmed.

Objective To explore clinical significence of soluble vascular cell adhesion molecular(SVCAM - 1),immunoglobulin A (IgA) anti- endothelial cells antibodies(AECA) in Henoch-Schonlein purpura(HSP) and their relationships. Methods SVCAM-1 were detected by ELISA between 55 cases with HSP (40 cases in acute stage and 15 cases in recovery) and 20 controls. Results The levels of serum SVCAM - 1 of the HSPN cases were significantly increased compared with the other HSP. In addition, the serum level of SVCAM - 1 in acute stage HSP children was significantly higher than that in recovery stage and normal controls. IgA AECA positive rate in HSPN was higher than that of without nephritis group. The level of serum SVCAM - 1 in IgA AECA positive children was higher than that of IgA AECA negative children. Conclusion SVCAM - 1 and IgA AECA may participate in the pathogegesis of HSP, and the level of molecule is correlated with the progress of HSP.

Objective To investigate the apoptosis of articular chondrocyte and the expression of Bcl-2, Bax, Fas and iNos in articular cartilage with Kashin-Beck disease(KBD) in order to understand the pathogenesis of chondronecrosis in KBD. Methods The collected samples of human articular cartilage were divided into two groups: control group (15 samples from 15 cases), KBD group (15 samples from 15 cases). KBD patients were diagnosed by "Pathological Criteria to Diagnose KBD in China". Chondrocyte apoptosis was detected by TUNEL staining, and the Bcl-2, Bax, Fas and iNos positive articular chondrocytes were stained by the B-SA of immunohistochemistry. Articular cartilage was classified three zones and the positive rate were counted by light microscope for cytoplasimic staining by polyclonal antibodies of Bcl-2, Bax, Fas and iNos and apoptotic chondrocytes by TUNEL. Results ① The percentage of positive apoptotic chondrocytes stained by TUNEL in the middle zone of articular cartilage from the KBD-children group(33.60±2.71%) was higher than that of the control (1.33±0.41% t=11.59, g=28, P<0.01). ②The percentage of chondrocytes staining for Bcl-2, Bax, Fas and iNos among the upper and the middle zone in KBD group were significantly higher than that of the control (t=11.75-18.65, g=14, P<0.01); the remarkable difference in the expression of Bcl-2, Bax, Fas and iNos among the upper, the middle and the deep zones was also seen in KBD articular cartilage (F=73.49-114.42, g=42, P<0.01), and staining for Bcl-2, Bax, Fas and iNos in KBD children was prominent in the upper zone(41.93±12.26%, 45.60±15.78%, 53.60±16.49%, 45.47±14.02%) and the middle zone(14.93±3.50%, 13.87±4.32%, 23.27±4.83%, 21.67±6.82%)of articular cartilage, respectively. Conclusion The chondrocyte apoptosis and the present of Bcl-2, Bax, Fas and iNos positive chondrocytes in articular cartilage of children with KBD were significantly higher than that of the control.

Objective To explore the clinical efficacy and safety of transcatheter absolute ethanol injection treatment on varicose veins of lower extremity.Methods twenty-there patients with 25 varicose veins of lower extremity were treated by puncture of great saphenous vein above 1—2 cm of complicated inner ankle,perforating catheter to the point below the 3—4 cm of the conjunction of great saphenous vein and Femoral vein and pressing the conjunction of these two veins.Under the monitor of DSA,inject the absolute ethenal slowly while retrieve the catheter little by little(one limb with varicose veins injected total volume 15—20 ml),in the mean time,using contrast agent to monitor the level of embolism until the formation of total embolism in the all great saphenous veins.Results All the cases were retrospectively followed up with CDFI examination after 3—12 months of the surgery,No blood flow were seen in the 25 embolismic great saphenous vein.Clinical symptom were alleviated obviously after 2—3 weeks of treatment;varicose veins were collapse after 3 to 7 days.Two eases of leg ulceration were healed after 4 to 6 weeks of operation.20 limbs were found mild swelling in the 2 day after the surgery.However,all the cases were disappeared after 1 to 2 weeks;4 treated limbs developed delayed paresthesia in the 3 day after the surgery,and recovered totally in the 2 weeks.No complications of deep vein thrombosis,lung thrombosis etc al,were found after operation.Conclusions Using transcatheter injection of absolute ethanol to treat varicose veins of lower extremity has the advantage of less invasion,more safety and low appearance of complications.The short term efficacy is solid while the long term effect needs further evaluation.

OBJECTIVETo study the changes of red cell immune function and T-lymphocyte subsets in children with bronchiolitis and their possible roles in the pathogenesis of bronchiolitis.

METHODSForty-five children with bronchiolitis and 30 healthy controls were enrolled. Red cell immune complex rosette (RBC-ICR) and red cell C3b receptor rosette (RBC-C3bRR) were detected. The percentages of CD3+, CD4+ and CD8+ cells were assayed by flow cytometry.

RESULTSRBC-C3bRR［(13.6 ± 6.2)% vs (18.0 ± 7.4)%] and the percentage of CD8+ cells [(21.6 ± 4.4)% vs (25.6 ± 5.2) %］ in the bronchiolitis group were lower than those in the control group (P<0.01). The percentage of CD3+ cells ［(59.9 ± 6.7)% vs (52.1 ± 8.3)%］ and CD4+ cells [(53.5 ± 6.2)% vs (46.8 ± 4.9)%] and RBC-ICR [(8.3 ± 3.5)% vs (6.1 ± 2.5)%] in the bronchiolitis group were higher than those in the control group (P<0.01). The percentage of CD4+ cells was positively correlated with RBC-ICR (r=0.63,P<0.05) and negatively correlated with RBC-C3bRR (r=-0.82,P<0.01).

CONCLUSIONSThere are dysfunctions of red cell immune and T-lymphocyte subsets in children with brochiolitis, which may play a role in the pathogenesis of brochiolitis.

Objective To study the action of apolipoprotein E genetic polymorphism on the efficacy of Tanshinol.Methods Through detecting the expression of low density lipoprotein receptor mRNA and 3-hydroxy-3 -methylglutaryl coenzyme A reductase mRNA in L -02 cells by reverse transcription-polymerase chain reaction , to compare the effect of different genetic subtypes of ApoE on Tanshinol.Results Apolipopro-tein E can weaken the induction of low density lipoprotein receptor ex-pression caused by Tanshinol.The weakening extent of apolipoprotein E 2 (Arg112Cys)was stronger than apolipoprotein E3 and apolipoprotein E4 ( Cys 158 Arg) ( P<0.01 ).Apolipoprotein E also can enhance the inhi-bition of 3-hydroxy -3-methylglutaryl coenzyme A reductase expres-sion, especially apolipoprotein E4 (P<0.01).But apolipoprotein E2 or apolipoprotein E3 can not have statistical significance ( P >0.05 ).Conclusion Both 112 and 158 site might be the key site that have effect on the efficacy of Tanshinol.

Obiective:To elucidate the phenotype and the genotype-phenotype correlations in Chinese patients with X-linked adrenoleukodystrophy(X-ALD).Methods:Clinical features of 40 Chinese patients with X-ALD were studied and mutation spectrums were investigated by polymerase chain reaction (PCR) and sequencing. Results:Among these patients, four were siblings from two unrelated families, the others were unrelated. There were 31 cases with childhood cerebral (CCALD), 8 cases with adolescent cerebral (ACALD) and 1 case with adrenomyeloneuropathy (AMN). Visual impairment, which presented in 12 cases (30%), was the most common initial symptom. Nine (69%) of 13 cases who had hydrocortisone and ACTH measured showed adrenal insufficiency. By follow-up date, 19 cases (47.5%) were dead. The interval from onset to death varied from 1 to 6 years and the average were 3.3 years. The mean age at death was 10.5 years. Eleven cases (27.5%) were in vegetable state. The mean interval from onset to apparently vegetable state was 2.8 years (range from 1 to 6 years). Four cases had progressive neurological disability. Four cases were lost follow-up. One case with CCALD and one case with ACALD progressed slowly. The courses of the disease of these two patients were 5 years and 15 years respectively. Thirty five mutations were identified in 40 cases. Most were located within exon 1-3 (40%, 16/40) and exon 6-8 (42%, 17/40). There is a distinct clustering of missense mutations in exon 6 (17%, 7/40). Five types of mutations were associated with CCALD, three with ACALD and a missense mutation was identified in the patients with AMN. The two patients with long disease courses had a missence mutation c.1559 T>A and a nonsense mutation c.1785 G>A respectively. The siblings with similar manifestations and onset age were observed in two families, whose mutations were c.887 A>G and c.1028 G>T. Conclusion:The phenotypes, disease severity and rate of neurodegeneration could not be predicted by the nature of mutations.
