The UHPLC-LTQ-Orbitrap high resolution mass spectrometer was used to explore the chemical compositions in safflower. The rapid separation of the compositions was conducted by the UHPLC, following by high resolution full scan and MS2 scan, under the positive and negative ion mode. The chemical formula of compositions were deduced by full scan data in less than 5, then the potential structures were confirmed by the MS2 data. Forty-nine compounds were detected, of which 26 was identified, and 5 compounds was validated by the standard substances.

Objective To evaluate the value of lymphoscintigraphy in diagnosis of chylous ascites in children.Methods Lymphoscintigraphy was done in 6 cases,computed tomography(CT) was done in 4 cases,X-ray exam was done 42 times.And their video repore were compared.Results Lymphoscintigraphy was done in 6 cases,5 cases′ results were positive which diagnosed chylous ascites,and their leaking positions were also found.Conclusion Lymphoscintigraphy has the qualitative and orientational effect on diagnosis of children with chylous ascites.

Objective To study the effects of rehabilitation(RT)on cardiac function in cerebral infarct (CIF)patients with cardiac insufficiency(CIS).Methods Fifty-nine CIF patients with CIS were randomly divid- ed into a treatment group(T group,n=29)and a control group(n=30),and all patients were treated with routine pharmacotherapy for 2 months.In addition,RT was administrated in the T group at the same time.The grading of the New York Heart Association(NYHA)and the changes in cardiac function associated index were observed in both groups before and after treatment.Results Compared with the control group,NYHA grades,left ventricle ejection fraction(LVEF),the levels of brain natriuretic peptide(BNP)in the blood plasma,and the 6min walking range of the T group patients were all significantly improved after treatment(P＜0.05).Conclusion RT can improve car- diac function in CIF patients with CIS.

OBJECTIVETo investigate the clinical outcomes of semicircular decompression in treating old thoracolumbar fractures and intractable neuropathic pain.

METHODSFrom September 2009 to September 2013, 21 patients with old thoracolumbar fracture and intractable neuropathic pain were treated with semicircular decompression. Among initial surgery, posterior pedicle screw fixation was used in these patients, with or without laminectomy. All patients were male, range in age from 20 to 28 years old with an average of (25.00±2.38) years. Vertebral body residual bone block resulted in intra-spinal placeholder more than 50%. All patients were complete spinal cord injury (ASIA grade) or cauda equina injury. VAS scores was from 6 to 10 points with the mean of 7.14±0.91. In these patients, MRI, CT, X-rays were performed; denomination and dosage of analgesics were recorded; nerve function and pain status were respectively evaluated by ASIA grade and VAS score before and after operation.

RESULTSAll patients were followed up from 8 to 32 months with an average of (17.29±6.02) months. All bone fragments of spinal canal were removed and spinal cord decompressions were achieved. At final follow-up, VAS scores were from 0 to 8 points with an average of (2.43±2.46) points, and were obviously reduced than peroperative data (P<0.05). Eleven cases of them stopped analgesic intake and 7 cases reduced using. Three patients' symptoms and VAS scores were not improved.

CONCLUSIONOld thoracolumbar fractures and intractable neuropathic pain need receive imaging examination as soon as possible and consider semicircular decompression therapy if bone fragments were in vertebral canal and spinal canal stenosis existed. This therapy can effectively relieve pain and profit nerve functional recovery.

BACKGROUND: In lumbar spondylolisthesis patients with severe osteoporosis, screw is easily loose and pul s out during reposition, or loss of reduction and internal fixation failure easily occur after repair. Therefore, it is very important to elevate the intensity of pedicle screw fixation during repair. At present, few studies concern application of bone cement screw enhancement technology in lumbar spondylolisthesis patients with osteoporosis. OBJECTIVE: To investigate the clinical value of augmented pedicle screw with polymethylmethacrylate for lumbar spondylolisthesis accompanied with osteoporosis. METHODS: From June 2009 to June 2011, 27 patients suffering from lumbar spondylolisthesis accompanied with osteoporosis were included in this retrospective study. These patients received augmented pedicle screw with polymethylmethacrylate. The levels of disability and pain were evaluated by Oswestry Disability Index and visual analog scale. The internal fixation and fusion were evaluated by radiological findings. Al complications were recorded. RESULTS AND CONCLUSION: Al cases were fol owed up for 15-37 months. Oswestry Disability Index and visual analog scale scores were significantly better in final fol ow-up than that pre-treatment (P < 0.05). Imaging results revealed that bone cement tightly connected to bone interface. The position of screw and bone cement was good. Symptomatic bone cement leakage was not found. No fixation failure was detected during final fol ow-up. Al patients achieved interbody fusion. These results suggested that polymethylmethacrylate bone cement could increase the gripping force of the pedicle screw in osteoporotic vertebral body. It is safe and effective to treat spondylolisthesis accompanied with osteoporosis with augmented pedicle screws. Satisfactory fixation stability and interbody fusion can be obtained.
