OBJECTIVETo evaluate the efficacy on hemiplegic spasticity after cerebral infarction treated with plum blossom needle tapping therapy at the key points and Bobath therapy.

METHODSEighty patients were collected, in compliance with the inclusive criteria of hemiplegic spasticity after cerebral infarction, and randomized into an observation group and a control group, 40 cases in each one. In the control group, Bobath manipulation therapy was adopted to relieve spasticity and the treatment of 8 weeks was required. In the observation group, on the basis of the treatment as the control group, the tapping therapy with plum blossom needle was applied to the key points, named Jianyu (LI 15), Jianliao (LI 14), Jianzhen (SI 9), Hegu (LI 4), Chengfu (BL 36), Zusanli (ST 36), Xiyangguan (GB 33), etc. The treatment was given for 15 min each time, once a day. Before treatment, after 4 and 8 weeks of treatment, the Fugl-Meyer assessment (FMA) and Barthel index (BI) were adopted to evaluate the motor function of the extremity and the activity of daily life in the patients of the two groups separately. The modified Ashworth scale was used to evaluate the effect of anti-spasticity.

RESULTSIn 4 and 8 weeks of treatment, FMA: scores and BI scores were all significantly increased as compared with those before treatment in the two groups: (both P<0. 05). The results in 8 weeks of treatment in the observation group were significantly better than those in the control group (all P<0. 05). In 4 and 8 weeks of treatment, the scores of spasticity state were improved as compared with those before treatment in the patients of the two groups (all P<0. 05). The result in 8 weeks of treatment in the observation group was significantly better than that in the control group (P<0. 05). In 8 weeks of treatment, the total effective rate of anti-spasticity was 90. 0% (36/40) in the observation group, better than 75. 0% (30/40) in the control group (P<0. 05).

CONCLUSIONThe tapping therapy with plum blossom needle at the key points combined with Bobath therapy effectively relieves hemiplegic spasticity in the patients of cerebral infarction and improves the motor function of extremity and the activity of daily life.

Objective To assess the anatomic morphology of the connective structures among brain ventricles and cerebrospinal fluid (CSF) movement in them by CSF spin-labeling MR imaging. Methods According to the order of registration, 50 healthy volunteers were randomly selected and received cerebrospinal fluid spin-labeling MR scan with time-spatial labeling inversion recovery single-shot fast spin echo sequence (SLIR-SSFSE). The tagged CSF was used as an endogenous tracer. The anatomic morphology of the connective structures of brain ventricles and the flow direction of CSF were observed. The longitudinal diameter and transverse diameter of bilateral foramina of monro, midbrain aqueduct, and the central and bilateral lateral apertures of the fourth ventricle of each subject were measured and calculated based on multiple measurements. The flow rate of CSF was calculated based on the flow distance of CSF in the connective structures between brain ventricles during different TI time. The mean value of each indicator was acquired. Results Two-way flow state of CSF was observed in all connective structures, including bilateral foramina of monro, midbrain aqueduct, and the central and bilateral lateral apertures of the fourth ventricle. On the coronal planes, foramen of monro appears as a "Y"-type tubular structure locating among the both sides of the anteriomedial thalamus and fornix, which connect upward with bilateral lateral ventricles and downward with the third ventricle. The longitudinal diameter and transverse diameter of the left side of foramen of monro were 3.50-5.50 mm[mean (4.37 ±0.47)mm]and 1.00-1.40 mm[mean(1.21 ±0. 13) mm], respectively. The longitudinal diameter and transverse diameter of the right side of foramen of monro were 4. 20-4. 80 mm[mean(4.42 ± 0.20) mm]and 1.00-1.60 mm[mean (1.21 ±0. 19) mm], respectively. On the sagittal planes, foramen of monro appeared as an oblique fine tubular structure with the angle of 55°-58° between the both sides. CSF flow velocity towards the foot was 1.61-2. 52 mm/s[mean (2. 00 ± 0. 17) mm/s]in the left side of foramen of monro and 1.93-2. 20 mm/s [mean (2.03 ±0.09) mm/s]in the right side of foramen of monro. On the sagittal planes, midbrain aqueduct appeared as a curved tubular structure through diencephalon, with the longitudinal diameter of 9.90-17.30 mm[mean(15.51 ± 1.70) mm]and the transverse diameter of 1.70-2.30 mm[mean (1.92 ± 0. 17)mm]. In midbrain aqueduct, CSF flow velocity towards the foot was about 5.00-8.74 mm/s[mean (7.84 ±0.86) mm/s]and towards the head was about 3.84-6.71 mm/s[mean (6. 01 ±0. 66) mm/s]. On the sagittal plane, the central apertures of the fourth ventricle appeared as a fork-like tubular structure, with a small bifurcation forward to the central canal of the medulla oblongata and a posterior branch downward to cerebellomedullary cistern. On the coronal plane, lateral apertures of the fourth ventricle appeaed as curved tubular structures connecting the lateral horn of the fourth ventricle and cerebellomedullary cistern. The longitudinal diameter and transverse diameter of the left lateral aperture were 6.30-14. 60 mm[mean (10.42 ±2.88) mm]and 1.00-1.50 mm[mean (1.24 ±0.18) mm],respectively; of the right lateral aperture, they were 6. 20-15.50 mm[mean (12. 13 ± 3.05) mm]and 1.00-1.40 mm[mean(1.19 ±0. 13) mm], respectively. The angle range between the left and right lateral aperture was from 87° to 114°. CSF flow velocity towards the foot was about 2. 89-6. 70 mm/s[mean (4. 78 ± 1.32) mm/s]in the left lateral aperture and 2. 84-7.11 mm/s[mean (5.56 ±1.40) mm/s]in the right lateral aperture. Conclusions CSF spin-labeling MR imaging could display the anatomic morphology of the connective structure among brain ventricles and could be used for noninvasively assessing CSF movement.

Objective To explore the clinical manifestations and recovery from neuroimaging abnormalities of acute disseminated encephalomyelitis (ADEM),in order to improve the understanding of ADEM.Methods A total of 47 children with ADEM in Department of Neurology,Children′s Hospital of Soochow University were followed up for 1 year.The clinical manifestations,auxiliary examination (especially neuroimaging),treatment and prognosis were analyzed.The recovery conditions from clinical and neuroimaging abnormalities were summarized.Results Among 47 cases,37 cases (78.72%) had prodromic infection history,and 5 cases (10.64%) had the history of vaccination.The clinical manifestations were varied,including 36 cases (76.60%) with somatic discomfort,30 cases (63.83%) with fever,30 cases (63.83%) with disturbance of consciousness,28 cases (59.57%) with epileptic seizure,24 cases (51.06%) with headache and dizziness,22 cases (46.81%) with nausea and vomiting,15 cases (31.91%) with dyskinesia,15 cases (31.91%) with cranial nerve injury,9 cases (19.14%) with incoordination,and 8 cases (17.02%) with mental and behavior disorders.Abnormal lesions presented multiple,asymmetric patchy and large patchy signal image showed by brain magnetic resonance imaging (MRI),and 7 cases (14.89%) involved the spinal cord.All patients received the treatment of Methylprednisolone [15-20 mg/(kg·d)] combined with intravenous gamma globulin (total 2 g/kg,3 to 5 days).The dose of Methylprednisolone gradually decreased after it had been used for 3 days.In the end,it was replaced by an oral administration of Prednisone [1.0-2.0 mg/(kg·d)],and the total treatment period was for 2-3 months.The follow-ups of 47 children with ADEM showed that the MRI lesions of all the children were reduced and the MRI lesions in 4 (8.51%) of them disappeared completely after 0.5 month of follow-up;the lesions disappeared completely in 13 cases (27.66%) after 1 month of follow-up;the lesions disappeared completely in 23 cases (48.94%) after 3 months of follow-up;the lesions disappeared completely in 32 cases (68.09%) after 6 months of follow-up;the lesions disappeared completely in 43 cases (91.49%) after 1 year of follow-up;and finally there were 4 cases (8.51%) with residual lesions.Conclusion The clinical manifestations of children with ADEM are varied.Most children with ADEM have a favorable prognosis.Imaging lesions of 68.09% of the cases completely disappeared after the onset of 6 months.Imaging lesions in 91.49% of the cases completely disa-ppeared at the onset of 1 year.Only a small fraction of patients present permanent lesions.

Purpose To investigate the clinicopathologic characteristics of colorectal metastatic tumors. Methods Cases which were clinically diagnosed as metastatic tumors to the colorectum were retrieved from the data base of the Department of Pathology, Peking U-niversity Third Hospital. The clinicopathologic features were studied and immunohistochemical stains were performed on some of the ca-ses for differential diagnosis. Results Fifty three cases which showed intestinal wall involvement were studied. In 43. 4% (23/53) of them, only serosa/subserosa was involved and mucosal involvement was observed in 37. 7% (20/53) of the cases. Sigmoid colon and rectum were the most frequently involved intestinal segments (24/53, 45. 3%). Female reproductive system was the most common ori-gin of the metastatic tumors (33/53, 62. 3%), followed by the digestive system (15/53, 28. 3%). The most common histological type was ovarian serous carcinoma (22/53, 41. 5%). 96. 2% (51/53) of the metastatic tumors were centrally located at the serosa/subserosa or the muscular propria and prominent lymphovascular invasion was observed in 26. 4% (14/53) of the cases. In cases with mucosal involvement, 35% ( 7/20 ) had foci that were lack of desmoplastic reaction, 20% ( 4/20 ) exhibited in-situ growth and/or paradoxical maturation of tumor cells which led to misdiagnosis in 2 of the 17 pre-operative biopsies. Conclusions Metastatic carcino-ma in the colorectum can be highly informed by predominantly involving the serosa/subserosa or muscular propria and prominent lym-phovascular invasion. In-situ growth and paradoxical maturation of tumor cells in the mucosa are diagnostic pitfalls in pre-operative co-lonic biopsy and should be aware in practice.

Objective To assess the efficacy of 308 nm excimer laser irradiation for the treatment of guinea pig model of vitiligo and its immunoregulatory effect on Treg cell and Th17 cell.Methods Vitiligo was induced in guinea pigs by hydroquinone bleaching,and they were randomly divided into an experimental group and a control group.There was also a normal control group.The experimental group was treated with a 308 nm excimer laser at the nidus of vitiligo; the two control groups were given no intervention.After 8 weeks of treatment,leukasmus of the different groups were compared.The mRNA expression of Foxp3 and IL-17 were measured by real-time fluorescence quantitative (RTFQ-PCR) and the expression of Foxp3 and IL-17 in the lesions were measured by immunohistochemistry staining.Results The effectiveness rate was 100％ in the experiment group.The results of RTFQ-PCR showed that the mRNA expression of Foxp3 in the experimental group and the vitiligo control group was significantly higher than the healthy control group (all P ＜ 0.05),being 0.33 ± 0.03 and 0.02 ±0.07 respectively,as was the mRNA expression of IL-17,being 0.21 ± 0.05 and 0.94 ± 0.06 accordingly; and the mRNA expression of IL-17 in the experimental group was significantly lower than the vitiligo control group(P ＜ 0.05).The immunohistochemical staining showed that Foxp3 and IL-17 protein was scattered in the lesions of the experimental group,while they were crowded in those of the vitiligo control group.Conclusion Laser irradiation might contribute to a therapeutic effect on vitiligo through modulating the balance of Treg and Th17 cells,at least in guinea pigs.

Objective To explore the effects of Levoeitirize dihydrochloride on interleukin-13(IL-13)and interleukin-18(IL-18)in the serum of the patients with cough variant asthma(CVA).Methods 70 cases with CVA were randomly devided into control group of 35 cases and treatment group of 35 cases.Control group was given Chlort rimeton and the treatment group was given Levocitirize dihydroehloride.The levels of IL-13 and IL-18 in the serum were measured before and after treatment.Results After treatment,the concentrations of IL-13 and IL-18 in patients in the treatment group were(46.7±17.3)ng/L and(145.2±27.1)ng/L，and those in the control group were(98.5±30.7)ng/L and(179.6±30.5)ne/L，which were significantly improved.Conclusion The treatmem of Levoeitirize dihydrochloride could improve the CVA through improving the production of IL-13 and IL-18.

Objective To study the relationship between the changes of diffusion tensor imaging(DTI)and diffusion tensor tractography(DTT)of optic radiation and the defect of visual field.Methods DTI and DTT were performed in 37 patients with invasion of the optic radiation by intracranial lesions and in 20 normal control group at 3.0T MR scanner,the visual fields of all cases were examined.The relativity between FA values,ADC values and mean sensitivity(MS)values,mean defect(MD)values of visual field and the relativity between the morphological change of optic radiation and the defect of visual field were analysed.Results In comparison with control group,FA values decreased and ADC values increased in subject group,there were statistically significant differences(P＜0.001)between them.In disordered group,FA values were positive correlation with MS values(r=0.718)and negative correlation with MD values(r=-0.694);ADC values were negative correlation with MS values(r=-0.625)and positive correlation with MD values(r=0.538).DTT showed that the ventral tracts of optic radiation were damaged which oppeared as the defect of ditto quadrant of bilateral field vision in 9 cases,the dorsal tracts and the lateral tracts of optic radiation were damaged which appeared as the defect of inferior quadrant of bilateral field vision in 7 cases,the optic radiations were damaged extensively that caused symmetric or asymmetric congruous hemianopia of bilateral field vision in 21 cases.Conclusion DTI and DTT of optic radiation are intimately correlated with the examined results of visual field,it will be a objective index to extimate the function and the morphological changes of optic radiation.

Objective To investigate the value of dynamic contrast?enhanced MRI (DCE?MRI) in the differential diagnosis of glioblastoma and brain metastases. Methods Twenty patients with high grade gliomas and 20 cases patients with brain metastases proved by surgery and pathology were collected, and patients were examined with conventional MRI and DCE?MRI preoperatively. The ROIs were manually placed in solid parts of the tumors and their surrounding tissues to calculate Ktrans, Kep and Ve values. The Ktrans, Kep and Ve values differences for the solid part and surrounding tissues of the two brain tumors were compared by two independent sample t test. The correlation between Ktrans of the solid parts of the two brain tumors and Ktrans, Kep and Ve values of their surrounding tissues were studied by Pearson correlation analysis. Results The Ktrans, Kep and Ve values of glioblastoma were(0.258 ± 0.063)min-1,(0.398 ± 0.082)min-1, 0.632±0.084, the Ktrans, Kep and Ve values of brain metastases were(0.233±0.053)min-1,(0.357±0.042)min-1, 0.672±0.113. There were no significant differences between the glioblastoma and brain metastases for Ktrans, Kep and Ve values(t=-1.354,-1.982, 1.276, all P>0.05). The Ktrans, Kep and Ve values of surrounding tissues of glioblastoma were(0.093±0.032)min-1,(0.411±0.089)min-1, 0.107±0.021, the Ktrans, Kep and Ve values of surrounding tissues of brain metastases were(0.033±0.010)min-1,(0.204±0.045)min-1, 0.069±0.017. The Ktrans, Kep and Ve values of surrounding tissues between glioblastoma and brain metastases had significant difference (t=-7.978,-9.303,-6.203, all P<0.05). The Ktrans of glioblastoma were correlated with Ktrans, Kep and Ve values of their surrounding tissues (r=0.759, 0.464, 0.651, all P<0.05); The Ktrans values of brain metastases had no relationship with Ktrans, Kep and Ve values of their surrounding tissues (P>0.05). Conclusion The DCE?MRI can quantitatively display the microvascular permeability and accurately evaluate the damage of blood?brain barrier of glioblastoma and brain metastases, which has an important value in studying biological characteristics and differential diagnosis of the two brain tumors.
