Objective To evaluate the roles of magnetic resonance imaging and proton magnetic resonance spectroscopy(1H-MRS) in the diagnosis of meningiomas. Methods 98 patients with meningiomas underwent conventional pre-contrast MR and contrast MR. Among them, 28 cases had two dimensional single voxel or multi voxel 1 H-MRS simultaneously both in the lesion's region and the contralateral side. Results On precontrast MR images of 98 cases, T1 WI showed 58.1% (61/105) isointensities, 31.4% (33/105) faintly low intensities and 10. 5% (11/105) mixed intensities; T2WI showed 40. 0% (42/105) isointensities, 41.0%(43/105) hyperintensities, 10.5% (11/105) faintly low intensities and 8.5% (9/105) mixed intensities. After administration of Gd-DTPA, the solid part of the tumors exhibited various enhancement in all the 98 cases.28 cases of MRS exhibited specific different spectral peaks, including increased of choline-containing compounds(Cho), absent or decreased of acetylaspartate(NAA), and the unchanged of creatine(Cr). The value of NAA, Cr, Cho, NAA/Cr, Cho/Cr, NAA/Cho in the tumor center of meningioma were 0. 09 ± 0.06,0.31 ± 0. 22, 0.46 ± 0. 16, 0.33 ± 0. 42, 1.50 ± 0. 68, 0. 15 ± 0.08, compared with the contralateral normal region, Cr has no significant difference (P ＞ 0. 05), NAA, Cho, NAA/Cr, Cho/Cr, NAA/Cho had significantly differences(P ＜ 0.05). Conclusion Conventional pre-contrast MR and contrast MR is the most important dignostic means for meningiomas, 1H-MRS combined with MRI can improve the diagnostic accuracy of meningiomas.

Objective To investigate the clinical features and LRRK2 gene mutation in patients with autosomal dominant familial Parkinson's disease (PD). Methods The clinical features of 16 autosomal dominant familial PD probands were analyzed in terms of age at onset, onset symptoms, UPDRS scores, response to the levodopa treatment and drug-induced dyskinesia. The LRRK2 gene exons 5,13,31,32,35,37,41 and 48 of 16 probands were sequenced after polymerase chain reaction. The novel mutation was further screened in 24D sporadic PD patients and 214 controls using PCR-RFLP for the genotypo frequency analysis. Results Clinically, most of 16 probands had late-onset age. Resting tremor (9patients, 56. 25%,t=0.558,P=0.679)and bradykinesia (9 patients,56.25%,t=0.369,P=0.454)were common onset symptoms followed by rigidity(6 patients,37.50%,t=1.324,P=0.735)and postural instability(5 patients,31.25%,t=2.369,P=0.956).Majority of them had good response to levedopa treatment and rare occurrence of drug-induced dyskinesia. Among the 16 autosomal dominant familial PD probands,6 variants were identified:c.457 T＞C(Leu153Leu),c.1432 G＞T(Asp478Tyr),c.5457 T＞C(Gly1819Gly),c.7153 G＞A(Gly2385Arg),IVS31+28 T＞G and IVS37+162 T＞C. The c.1432G＞T(Asp478Tyr)variant was a novel mutation and it was not detected in 240 sporadic PD patients and 214 controls. The reported mutations associated with the PD, such as Arg1441 Cys/Gly/His, Arg1514Gln, Tyr1699Cys, Ile2012Thr, Gly2019Ser and Ile2020Thr,were not found in our study. Conclusions The autosomal dominant familial PD patients present with classical symptoms of PD and bear the LRRK2 variantsAsp478Tyr and Gly2385Arg.

OBJECTIVE: To observe the relationship between the analgesic effect of balance acupuncture and functional changes in brain in patients with migraine without aura. METHODS: A total of 40 cases of migraine without aura were equally randomized into a headache-acupoint group and a sham-acupoint group. When acupuncture given, a filiform needle was inserted into the headache-acupoint (the midpoint of the depression region anterior to the juncture of the first and second metatarsal bones on the dorsum of the foot) or the sham point (the midpoint of the depression region anterior to the juncture site between the 3rd and 4th metatarsal joints of the dorsum of the foot) about 25-40 mm deep and manipulated for a while till the patient experienced feelings of electric shock and numbness, then withdrawn immediately. The treatment was conducted once daily for 4 weeks. The visual analogue scale (VAS) was used to evaluate the severity of pain, and the regional homogeneity (ReHo) analysis of resting state functional magnetic resonance imaging (fMRI) was used to assess changes of the spontaneous brain activity. RESULTS: After acupuncture, the analgesic effect of headache-acupoint was better than that of the sham-acupoint in both intervention stage and the follow-up stage (P< 0.05), and was also stronger in the intervention stage than in the follow-up stage (P<0.05). There was no significant difference in the analgesic effect between the intervention stage and the follow-up stage in the sham-acupoint group (P>0.05). Compared with pre-intervention, 4-weeks' intervention at the headache-acupoint showed an increase of ReHo values in the anterior cingulate gyrus, anterior central gyrus, superior orbital frontal gyrus, insula, inferior lobule, left anterior cingulate gyrus, ventral lateral nucleus and ventral posteromedial nucleus of the thalamus, pontine nucleus, cerebellar tonsils and orbital frontal inferior gyrus of the brain (P<0.05), and a decrease of ReHo values in the right brain bridge, central posterior gyrus, posterior cingulate gyrus, left central anterior gyrus, posterolateral nucleus of thalamus, and hippocampus (P<0.05), separately. In the sham-acupoint group, the ReHo value was increased in the right tongue gyrus, the left anterior lobe, the anterior cingulate gyrus and the lower occipital gyrus of the brain (P<0.05), and reduced in the left ventral posterolateral nucleus of the thalamus, separately (P<0.05). CONCLUSION: Balance acupuncture stimulation of headache acupoint has an analgesic effect in migraine patients without aura, which may be related to its effect in regulating resting state brain function of the limbic-system-dominated multiple brain regions.
