Objective To explore the value of immunofluorescent technique for clinical diagnosing Duchenne muscular dystrophy(DMD),Becker muscular dystrophy(BMD) and Limb-girdle muscular dystrophy(LGMD).Methods Immunofluorescent technique was applied,and the expressions of Dys1,Dys2,Dys3 monoclonal antibodies and ?-,?-,?-sarcoglycan(SG) polyclonal antibodies against dystrophin,?-SG,?-SG,?-SG in musculomembranes of frozen section specimens from 25 patients(10 cases of DMD,4 cases of BMD and 11 cases of LGMD) were detected.Results 10 DMD patients had negative staining of dystrophin,and 4 BMD patients had discontinuous or a patchy positive staining pattern.All LGMD patients had positive dystrophin staining.There was one patient presented negative staining of ?-SG and ?-SG,respectively.Conclusions Detecting of dystrophin by immunofluorescent technique is special and helpful in diagnosing and classifying DMD/BMD.At present,SG may not be used in diagnosing the LGMD patients.

Objective To explore the level and main functions of P-type ATPase7B in hepatic cells of patients with hepatolenticular degeneration(HLD).Methods The hepatic cells from 5 normal controls and 9 patients with HLD were cultured in vitro. P-type ATPase7B levels in hepatic cells were examined and compared by SDS-PAGE and Western-blot techniques.Results Compared with the controls, 9 patients displayed various changes of electrophoresis strip. Almost normal strips at 155?103 were found in 3 cases, no strip was found in 1 case, and thinner and lighter strips were showed in the remain 5 cases. 6 cases presented abnormal specific reaction strips.Conclusion Mutations of gene ATPase7B in HLD patients cause change of P-type ATPase7B in quantity and quality, thus leads to dysmetabolism of copper.

Objective To study the clinical efficacy of electromyography biofeedback on dystonia after hepatolenticular degeneration.Methods 40 patients with dystonia after hepatolenticular degeneration were divided into treatment group (n=20) and control group (n=20).All patients were treated with copper-cleaning, clonazepam and benzhexol hydrochloride etc., and acupuncture. The treatment group wastreated with electromyographic biofeedback in addition. They were assessed with modified Ashworth scale, modified Barthel index, and ankledorsiflexion active range of motion. Results The lower extremities function of all patients improved after treatment (P<0.05) and thetreatment group improved more than the control group (P<0.05). Conclusion Electromyography biofeedback is more effective to improvethe lower extremities function and activity of daily living in patients with hepatolenticular degeneration following dystonia.

Objective To investigate the effect of electroacupuncture on expression of growth associated protein-43 (GAP-43) and Nogo-A in brain after focal cerebral ischemia/reperfusion in rats. Methods 48 male Sprague-Dawley rats were randomly divided into sham group, model group and electroacupuncture group, and the latter two were modeled as middle cerebral artery occlusion and reperfusion with nylon monofilament suture. Electroacupuncture was performed 90 min after modeling in the electroacupucture group at acupoints of Neiguan (PC06), Shuigou (DU26), Sanyinjiao (SP06), Baihui (DU20), for 30 min, once a day. The sham group and the model group were conventionally fed in cages without any intervention. 8 rats of each group were assessed with Longa's score, and the expressions of GAP-43 and Nogo-A were detected with immunohistochemistry 7 d and 14 d after modeling respectively. Results The sham group presented no neurological symptoms. There was not different in Longa's score between the model group and the electroacupuncture group 7 d after modeling (P>0.05), but was different 14 d after modeling (P<0.05). GAP-43 positive cells was not found in the sham group, but could be found around cerebral ischemia 7 d after modeling, which decreased 14 d after modeling in the model group. GAP-43 positive cells increased significantly in the electroacupuncture group compared with the model group at each time (P<0.01). Nogo-A positive cells was few found in the sham group, and was more in the model group (P<0.01). The expression of Nogo-A decreased significantly in the electroacupuncture group compared with the model group at each time (P<0.01). Conclusion Electroacupuncture can improve neurological function of focal cerebral ischemia/reperfusion rats, which may be associated with the increase of GAP-43 and descrease of Nogo-A in peri-infarct regions

Objective To study the regional cerebral blood flow (rCBF) and correlated factors in patients with hepatolenticular degeneration (HLD).Methods The rCBF of lentiform nucleus,thalamus and other sites in 14 patients with HLD of cerebral type (cerebral type group) and 10 patients with HLD of non-cerebral type (non-cerebral type group) were determined by magnetic resonance-perfusion imaging technology,meanwhile 13 healthy volunteers were selected as control group,and calculated the relative regional cerebral blood flow (rrCBF) for avoiding perfusion time lag.The correlation between the clinical symptom scores,the content of urinary copper,duration and rrCBF in HLD patients were evaluated.Results The rrCBF of cerebral type group in the left and right frontal lobe,temporal lobe,lentiform nucleus,caudate nucleus,thalamus,midbrain,pons and the left hippocampus,cerebellar cortex,dentate nucleus were lower than those of control group (1.91 ±0.35 vs.2.44 ±0.64,1.80 ±0.30 vs.2.37 ±0.65,1.37 ±0.35 vs.2.14 ±0.91,1.58 ±0.52 vs.2.39 ±0.99,1.61 ±0.38 vs.2.59 ±0.74,1.52 ±0.64 vs.2.63 ±0.73,1.88 ±0.32 vs.2.61 ±0.67,1.70 ±0.40 vs.2.35 ±0.50,1.48 ±0.13 vs.2.01 ±0.59,1.46 ±0.38 vs.2.38 ±0.99,1.47 ±0.55 vs.2.02 ±0.72,1.27 ±0.48 vs.1.91 ±0.51,1.24 ±0.38 vs.1.47 ±0.29,1.25 ±0.39 vs.1.53 ±0.37,1.74 ±0.27 vs.2.40 ±0.89,1.79 ±0.50 vs.2.22 ±0.66,2.15 ±0.41 vs.2.64 ± 0.61),and there were significant differences (P ＜ 0.05 or ＜ 0.01).There were no significant differences in the rrCBF of the parietal and occipital lobe,etc between cerebral type group and control group (P ＞ 0.05).The rrCBF of cerebral type group in the left and right lentiform nucleus were lower than those of non-cerebral type group (1.61 ± 0.38 vs.1.94 ± 0.58,1.52 ± 0.64 vs.1.99 ± 0.59),and there were significant differences (P ＜ 0.05).The clinical symptom scores were positively correlated with the rrCBF of the left and right lentiform nucleus in 24 patients with HLD (r =-0.792 and-0.764,P ＜ 0.01),the content of urinary copper and duration had no correlation with the rrCBF of the left and right lentiform nucleus(P ＞ 0.05).Conclusions The rCBF of cerebral type and non-cerebral type HLD is significantly reduced,cerebral type patients have lower rCBF than non-cerebral type patients.The rCBF is correlated with the clinical symptom scores.

Objective To establish a fast and effective gene diagnosis method for Wilson's disease(WD) patients by double PCR-SSCP technology.Methods We amplificated exon8 and exon12 of ATP7B gene by double PCR from genomic DNA of 140 unrelated WD patients and 30 normal controls,then used SSCP technology to screen them.At last we identificated these patients' mutation features by direct sequencing.Results No abnormality shift was found in 30 controls.In 140 patients,we found 7 types of abnormal mobility shifts in 66 cases(47.14%).In subsequent direct sequencing,mutation rate of Arg778Leu/Gln was 37.14%(52/140),and Thr935Met was 12.86%(18/140).Conclusion Double PCR-SSCP diagnosis technology is a effective method which can improve diagnosis rate for Wilson disease.

Objective To examine the brain metabolic changes in WD patients receiving copper chelation by us?ing 1H-MRS. Method Thirty-nine patients with WD was randomly divided into four groups: non-brain type group (18 cases), brain type prior-treatment group and short-term treatment group (21 cases), long-term treatment group (20 cases) from short-term treatment group, and 20 healthy volunteers served as a control group. 1H-MRS and MRI were performed on patients on 1.5/MR/MRS system to detect these above-mentioned items before and after treatment. Result The mean of NAA/Cr was significantly lower in the left putamen and head of the caudate nucleus than in the left basal ganglion in the 39 patients with WD. The mean of NAA/Cr and Cho/Cr in the left putamen and basal ganglion was significantly lower in non-brain type group than in control group(P<0.01). The mean of NAA/Cr Cho/Cr and NAA/Cho in the left putamen,head of the caudate nucleus and basal ganglion were significantly lower in brain type group than in control group(P<0.01 or P<0.05). The mean of NAA/Cr in the left putamen was much lower in brain type group than in non-brain type group (P<0.01). The mean of NAA/Cr, Cho/Cr and NAA/Cho of short-term treatment group in the left putamen, head of the caudate nucleus and basal ganglion was not significantly different between brain type group and short-term treatment group(P>0.05). The mean of NAA/Cr and NAA/Cho in the left putamen and basal ganglion was much higher in long-term treatment group than in brain type group(P<0.01 or P<0.05). The mean of Cho/Cr in the left head of caudate nucleus were much higher after treatment compared with prior-treatment group(P<0.05). The mean of NAA/Cr in the left putamen, head of the left caudate nucleus and basal ganglion in all groups was negatively correlated with course of the disease. Conclusion There are significant differences in brain metabolism among different type of WD. The long-term but not short-term copper chelation significantly improves brain metabolism. NAA/Cr may be used as a non-invasive indicator to examine the efficacy of treatment.
