Objective:To observe the efficacy of acupuncture at points of Shaoyang meridians plus moving cupping on neck and shoulder for migraine. Methods:A total of 64 migraine cases were randomly allocated into an observation group and a control group, 32 cases in each group. Random number table method was used in allocation. Acupuncture at points of Shaoyang meridians and cupping on neck and shoulder were used for cases in the observation group, which contain acupuncture 5 times a week and cupping once a week. Oral flunarizine hydrochloride capsules were used for cases in the control group, 10 mg for each dose, 1 dose a day. 2 weeks constitutes a course of treatment. The patients were treated for two courses of treatment in both groups. After that, the changes of visual analogue scale (VAS) and the migraine disability assessment questionnaire (MIDAS) were observed, as well as the clinical efficacy. Results:The total effective rate and recovery and marked effective rate in the observation group were 93.8% and 71.0% respectively, versus 78.1% and 43.8% in the control group, showing statistical significant differences (both P<0.05). There were significant decreases in VAS and MIDAS scores after treatments in both groups (both P<0.05). VAS and MIDAS scores in the observation group were significantly different from those in the control group (both P<0.05). Conclusion: Combining acupuncture at points of Shaoyang meridians and cupping on neck and shoulder can relieve headache and reduce influence of migraine on life. It can produce a better efficacy than oral flunarizine hydrochloride capsules in treating migraine patients.

Tetrahydrobiopterin (BH4) is an essential cofactor for all three nitric oxide synthase (NOS isoforms), which plays an important role in vascular diseases. GTP cyclohydrolase 1 (GCH 1) is the first-step and rate-limiting enzyme for BH4 biosynthesis in its de novo pathway. Common GCH1 gene variant C+243T in the 3'-untranslated region predicts NO excretion. The present study examined the predictive role of GCH 1 gene 3'-UTR C+243T variant in the long-term outcome of ischemic stroke. A total of 142 patients with first-onset ischemic stroke were recruited and detected for genotype of GCH1 3'-UTR C+243T by a TaqMan SNP Genotyping assay. Subsequent vascular events and death were determined over a 5-year follow-up period. The frequency of GCH1 3'-UTR +243 C/T or T/T genotype was significantly increased in patients with endpoint events as compared with those without events (74% vs 57.8%, P=0.06). Cox regression survival analysis indicated that an increased probability of death or new vascular events was found in patients with GCH1 3'-UTR +243 C/T or T/T genotype compared with those with GCH1 3'-UTR C/C genotype (40.6% vs 25.5%), GCH1 3'-UTR +243 C/T or T/T genotype relative to GCH1 3'-UTR C/C genotype was associated with the increased risk of death or vascular events even after adjustment for other risk factors (OR=2.171, 95% CI: 1.066-4.424, P=0.033). It was concluded that GCH1 3'-UTR C+243T variant was an independent predictor of worsening long-term outcomes in patients with first-onset ischemic stroke.

Objective To determine the significance of renin angiotensin system (RAS) expressed on placenta in pregnancy induced hypertension (PIH). Methods The expression of placental angiotensin Ⅱtype 1 receptor (AT 1R) and angiotensinogen (AGT) in patients with PIH ( n =20) were investigated and compared with controls ( n =15) using immunohistochemistry and semi quantitative reverse transcription polymerase chain reaction (RT PCR). Results AT 1R was mainly found in the syncytiotrophoblasts, cytotrophoblasts,the vascular endothelial cells and smooth muscle cells. The expression of AT 1R in PIH group (112.43?11.75) was higher than that of control group (170.47? 10.59) ( P

Cyclophosphamide (CPA) is the most common alkylating antineoplastic agent, as well as a strong immunosuppressant that is frequently applied to autoimmune diseases and organ transplantation. It is metabolized by cytochrome P450 oxidases (CYPs) to its active metabolite which played a critical role in therapy. CPA has serious and even fatal side effects, and its efficacy and adverse reactions are significantly varied among individuals. In this review, the association of the genetic polymorphisms in the metabolic enzymes and transporters involved in the disposition of CPA with the efficacy and adverse effects of CPA were summarized, thereby providing fundamental reference for further pharmacogenomic study of CPA.

OBJECTIVETo investigate the correlation between galectin-1 expression and the biological behaviors of human colorectal carcinoma.

METHODSSP immunohistochemistry was used to detect the expression of galectin-1 in 158 paraffin-embedded specimens including 30 normal mucosa, 25 adenoma, 65 colorectal carcinoma and 38 metastatic tumor specimens. Real-time RT-PCR was used to detect galectin-1 mRNA expression in 32 fresh specimens of colorectal carcinoma and normal mucosa.

RESULTSThe positive expression level of galectin-1 was significantly different between normal mucosa, adenoma, colorectal carcinomas and metastatic tumors, with positivity rate of 0, 8%, 66% and 86%, respectively (P<0.05). Galectin-1 expression in moderately or well differentiated colorectal carcinomas was significantly lower than that in poorly differentiated ones (P=0.031), and its expression in invasive carcinomas was significantly higher than that in non-invasive carcinomas (P=0.000). Galectin-1 expression in colorectal carcinomas was significantly related with lymph node metastasis (P=0.004). In poorly differentiated colorectal carcinomas, the expression of galectin-1 mRNA was about 2.27 times that in moderately or well differentiated colorectal carcinomas (P=0.00); galectin-1 mRNA expression in invasive carcinoma was 1.98 times that in non-invasive carcinoma (P=0.002). In tumors with lymph node metastasis, galectin-1 mRNA expression was 1.42 times that in tumors without metastasis (P=0.018).

CONCLUSIONGalectin-1 can be involved in the development and progression of colorectal carcinoma, and may relate to the infiltration, differentiation and lymph node metastasis of colorectal carcinoma.

Objective To investigate how gene silence of CD40 by small interfering RNA(siRNA)influences the balance between Th1 / Th2 and Th17 / Treg in rats with experimental autoimmune myocarditis(EAM). Methods Lewis rats were divided into a normal - control group,EAM group,CD40 siRNA - therapy group and siRNA - control group by using random number table. EAM,CD40 siRNA - therapy and siRNA - control groups were immunized on day 0 and day 7 with purified porcine cardiac myosin to establish EAM,and CD40 siRNA was administered intravenously on day 7. The basic data of each group were observed,and the rats were executed on day 21 to study the pathology of myo-cardial tissues and the myocardial histopathology scores were calculated,and than the changes in electrocardiograms (ECG)and echocardiogram were recorded. Enzyme - linked immunosorbent assay(ELISA)was used to determine the levels of interferon(IFN) - γ,interleukin(IL) - 10,IL - 17 and transforming growth factor(TGF)- β in peripheral blood. Results (1)The overall incidence of EAM,CD40 siRNA - therapy and siRNA - control group was 100% ,and no rats died from day 0 to day 21.(2)There were only 2 premature rats in EAM and siRNA - control groups,and the ECGs of normal - control group and CD40 siRNA - therapy group were normal.(3)The echocardiogram of EAM,CD40 siRNA - therapy and siRNA - control group,displayed the left ventricular dilatation,hypertrophy of the left ventricle, the weakening of the left ventricular wall motion,and heart failure,and pericardial effusion was discovered. The left ven-tricular fractional shortening(LVFS)and the left ventricular ejection fraction(LVEF)of rats treated by CD40 siRNA were higher than those of rats in the EAM group[(46. 70 ± 8. 25)% vs(34. 28 ± 11. 81)% ,(80. 92 ± 11. 76)% vs (64. 03 ± 12. 60)% ,F = 0. 652,0. 234,all P ﹤ 0. 05].(4)Pathologic examination of the EAM group,CD40 siRNA therapy group and siRNA control groups,showed myocardial fiber fracture,myocardial tissue necrosis and inflammatory cell infiltration. But myocardial tissue pathological scores of the cardiac tissue of CD40 siRNA therapy group was lower than those of the EAM group(2. 10 ± 1. 07 vs 3. 40 ± 0. 72,F = 1. 290,P ﹤ 0. 05).(5)ELISA method examination re-vealed that the levels of IFN - γ,IL - 4,IL - 17 and TGF - β in EAM group were increased compared with those of nor-mal control group[(1 245. 55 ± 244. 56)ng/ L vs(501. 53 ± 18. 93)ng/ L,(78. 03 ± 10. 47)ng/ L vs(30. 77 ± 1. 74)ng/ L,(80. 82 ± 13. 33)ng/ L vs(27. 98 ± 3. 01)ng/ L,(156. 27 ± 12. 11)ng/ L vs(4. 33 ± 0. 79)ng/ L,t =7. 408,10. 764,9. 250,30. 608,all P ﹤ 0. 05]. However,the levels of IFN - γ and IL - 17 in CD40 siRNA therapy group were lower than those in the EAM group[(940. 62 ± 128. 40)ng/ L vs(1 245. 55 ± 244. 56)ng/ L,(60. 42 ± 12. 40) ng/ L vs(80. 82 ± 13. 33)ng/ L,t = 2. 704,2. 745,all P ﹤ 0. 05],while the levels of IL - 4 and TGF - β were higher [(97. 91 ± 13. 62)ng/ L vs(78. 03 ± 10. 47)ng/ L,(178. 84 ± 12. 10)ng/ L vs(156. 27 ± 12. 11)ng/ L,t = 2. 835, 3. 229,all P ﹤ 0. 05]. Conclusions The administration of CD40 siRNA markedly reduces myocardial inflammation of EAM rats and improves their cardiac function,which can be explained by Th1 - type and Th17 - type cytokines inhibi-ted,Th2 - type and Treg - type cytokines increased,and so then the imbalance of Th1 / Th2 and Th17 / Treg corrected.

Objective To investigate changes of the interhemispheric coordination integrity in patients with hemi-parkinsonism using resting-state functional magnetic resonance imaging(rs-fMRI) homotopy technique called voxel-mirrored homotopic connectivity(VMHC).Methods Sixteen Parkinson disease(PD) patients with right body side motor symptom onset(RPD),15 patients with left side onset(LPD),and 19 age-,gender-,and education-matched healthy controls(HC) were included in this study.rs-fMRI scanning and pre-processed the raw data were performed.Then by using analysis of variance(ANOVA) and two sample t tset,we performed VMHC analyses on rs-fMRI data of these participants(P＜0.05,corrected with AlphaSim,clusters≥16 voxels).Exploratory linear correlations analyses were performed between the VMHC of regions showing significant group differences and the clinical features of LPD or RPD patients.Results Compared with HCs,patients with LPD had significantly reduced VMHC in visual regions,sensorimotor regions,and the cerebellar cortex(voxels size of 17-77,t=-5.06--3.42,P＜0.05).Patients with RPD exhibited decreased VMHC in the prefrontal cortex and sensorimotor regions.Both LPD and RPD groups had increased VMHC in subcortical regions.When compared with the RPD group,the LPD group displayed decreased VMHC in the visual regions,sensorimotor regions(voxels=16 and 18; t=-3.68and-3.87,respectively,both P＜0.05) and increased VMHC in the supramarginal gyrus(voxels=4,t=4.72,P＜0.05);ROI-based correlation analyses indicated that the VMHC in the inferior occipital gyrus and the postcentral gyrus was negatively correlated with the BDI-Ⅱ scores in the LPD group(r=-0.58 and-0.59,respectively; both P＜0.05),and positively correlated with the MMSE scores(r=0.56 and 0.52,respectively;both P＜0.05).In the RPD group,a positive correlation was found for the VMHC in the supramarginal gyrus and the illness duration(r=0.56,P＜0.05) and for the VMHC in the postcentral gyrus and the(mini-mental state exam) MMSE(r=0.53,P＜0.05).Conclusions The differential pattern of deficits in the interhemispheric coordination integrity in hemi-parkinsonism reflected by VMHC may provide insights into the neurological pathophysiology underlying the asymmetry of symptom appearance in PD.

Objective To explore the imaging manifestations of low-grade central osteosarcoma (LGCOS) and discuss their pathological features.Methods Twelve patients of LGCOS proved by surgery and pathology were analyzed retrospectively and a review of related literature was performed.All twelve patients had plain X-ray,1 1 patients CT examination,and 10 patients contrast-enhanced MR scan.Imaging features of the LGCOS were summarized,their clinical and pathological manifestations were discussed for differential diagnosis.Their prognosis was evaluated with followed up examination.Results Of the 12patients with LGCOS,six tumors were located in the distal femur,3 in the proximal tibia,2 in the proximal femur and 1 in the talus.The radiographic features of LGCOS were variable.There were 7 patients with predominantly osteolytic destruction,3 patients with mixed sclerotic and lyric changes,with well-defined margins,2 patients with Osteogenic changes on X-ray.On CT,9 patients showed a clear cortical breach,5 patients with soft tissue involvement,6 patients with peripheral incompletely sclerotic zone,2 patients with periosteal reaction.On MRI,there were 10 patients with abnormal signal in medullary cavity,8 patients with soft tissue masses,and all 10 patients exhibited contrast enhancement.The microscopic features of LGCOS were characteristically bland,comprising spindle cells arranged in interlacing fascicles in a heavily collagenous background with variable bone or osteoid production.There were mild nuclear atypia and rare mitoses.In four patients,misdiagnoses were made by biopsy or surgical pathology as fibrous dysplasia or fibrous histiocytoma and other benign lesions,all four patients had postoperative recurrence.Conclusions LGCOS should be differentiated form fibrous dysplasia,non-ossifying fibroma,and other benign lesions.An accurate diagnosis can be made in most cases by careful pathological and radiological correlation.
