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.

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.

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

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.

Objective To determine the utility of diffusion-weighted magnetic resonance imaging ( MR DWI ) in detecting tumor necrosis with histological correlation after neoacljuvant chemotherapy. Methods Conventional MRI and DWI were obtained from 36 patients with histological proven esteosarcoma. Magnetic resonance examinations were performed in all patients before and after 4 cycles of preoperative neoadjuvant chemotherapy. Apparent diffusion coefficients (ADC) were calculated. The degree of tumor necrosis was assessed using the histological Huvos classification after chemotherapy. T-test was performed for testing changes in ADC value between the 2 groups. P value less than 0. 05 were considered as a statistically significant difference. Results The differences in ADC between viable [ (1.06±0. 30) ×10-3mm2/s ] and necrotic [ (2. 39±0. 44 )×10-3mm2/s] tumor were significant (t= 3. 515,P<0. 05). Changes in ADC value was greater in good responses to neoadjuvant chemotherapy than in poor responses, the ADC value in good responses was increased from (1.18±0. 19)×10-3mm2/s to (2. 27±0. 20)×10-3mm2/s, the corresponding value in poor responses was increased from (1.45± 0.11)×10-3mm2/s to (1.83±0. 16)×10-3mm2/s, There was significant difference in changes of ADC values between good responses and poor responses ( t = 4. 981, P < 0. 01 ). Conclusion Diffusion-weighted MRI permits recognition of tumor necrosis induced by chemotherapy in osteosarcoma. DWI is correlated directly with tumor necrosis. They have potential utility in evaluating the preoperative chemotherapy response in patients with primary osteosarcoma.

The study aims to develop an LC-MS/MS method for the simultaneous determination of amygdalin and paeoniflorin in urine samples, and to investigate their urinary excretion characteristics in healthy volunteers after intravenous infusion administration of Huoxue-Tongluo lyophilized powder for injection (HTLPI). The urine samples were extracted by methanol, and then separated on a Hedera ODS-2 column with a mobile phase of acetonitrile and 5 mmol · L(-1) ammonium acetate buffer solution containing 0.05% formic acid (20:80). Electrospray ionization source was applied and operated in the positive ion mode using MRM. The method exhibited good linearity over the concentration range of 0.03 -40 µg · mL(-1). The values on both the occasions (intra- and inter-day) were all within 15% at three concentration levels. No matrix effect and carry-over effect were observed. Amygdalin and paeoniflorin were stable in human urine under different storage conditions. Approximately 79.6% of the administered amount of amygdalin was excreted unchanged in urine within 24 h and which was 48.4% for paeoniflorin. The developed LC-MS/MS method can be applied to evaluate the urinary excretion of amygdalin and paeoniflorin.
