Objective To investigate the effect of Epimedium flavanoids (EF) on neuro-inflammatory reaction in Alzheimer disease (AD) mice model.Methods β-amyloid1-40 (Aβ1-40) was injected to the right lateral ventricle of 2-month-old male ICR mice to induce AD model. Morris water maze and step-through tests were used to measure the learning and memory ability of mice. The concentrations of interleukin-1β (IL-1β) and tumor necrosis factor α (TNF-α) in the hippocampus were determined by radioimmunoassay. The expression of glial fibrillary acidic protein (GFAP) positive cells (astrocytes) was detected by immunochemistry staining.Results Compared with the sham-operation group, the learning and memory ability decreased (P<0.05, P<0.01), the concentrations of IL-1β and TNF-α in the hippocampus increased (P<0.01) and the expression of astrocytes in the hippocampus elevated (P<0.05) in Aβ1-40 injection model mice. Intragastric administration of EF (100 and 300 mg/kg) for 3 weeks significantly improved the learning and memory ability (P<0.05, P<0.01), decreased IL-1β and TNF-α concentrations in the hippocampus (P<0.05, P<0.01) and inhibited the expression of astrocytes in the hippocampus (P<0.05), compared with Aβ1-40 injection model mice.Conclusion EF can decrease the inflammatory reaction in the brain of mice induced by Aβ.

Objective To determine whether isometric handgrip exercise can increase collateral flow to the ischemic myocardium in acute coronary occlusion patients with coronary artery disease (CAD).Methods Sixty-five patients with one-vessel CAD were randomly assigned to either an isometric exercise (IME) group or no-exercise (NE) group.Patients in the IME group performed isometric handgrip exercises (50％ of the maximum voluntary contraction) during 1 min of coronary balloon occlusion.Patients in the NE group remained sedentary during the procedure.The collateral flow index (CFI),heart rare (HR),systolic blood pressure (SBP) and diastolic blood pressure (DBP) were determined prior to and at the end of 1 min of coronary occlusion.Results In the IME group the average CFI improved significantly more during the occlusion than in the NE group.The differences in HR,SBP and DBP were also significantly grcatcr in the CFI group than in the NE group controls.Conclusion Isometric exercise can induce significantly increased coronary collateral flow in CAD patients during acute vessel occlusion.

ObjectiveTo observe the effect of auricular acupuncture combined with physical therapy on motor function of stroke patients.Methods40 stroke patients were divided randomly into trial group and control group with 20 cases in each group. Patients of trail group were treated with auricular acupuncture combined with physical therapy; cases of control group were treated only with physical therapy. Motor function of all patients were assessed with Fugl-Meyer Assessment (FMA) before and after treatment.ResultsFMA scores of patients of trial group increased significantly compared with that of control group (P<0.01).ConclusionEffect of auricular acupuncture combined with physical therapy is better than that of single physical therapy on motor function of the stroke patients.

Objective To detect the mutations in RECQL4 gene in a Chinese patient with Rothmund- Thomson syndrome (RTS). Methods Blood samples were collected from a sporadic patient with RTS, his unaffected parents and 30 unrelated population-matched controls. DNA was extracted, and all the coding sequences of RECQL4 gene were amplified by PCR. Direct sequencing was performed with the amplicons to detect the possible mutations in these subjects. Results Two mutations, i.e., IVS11-1G > A and 3401 A >T, which resulted in a premature termination codon at amino acid 560, were found in the RECQL4 gene of the patient. His father was heterozygous for IVS11-1G > A, and his mother for 3401 A>T. Meanwhile, neither of the two mutations were observed in 30 unrelated normal control individuals. Conclusion Two mutations, including IVS11-1G>A and 3401 A>T are present in the RECQL4 gene of the sporadic patient with RTS.

0.05), and the change of kidney tissue morphology of groups C, D, E was little. Conclusion Xiaojiyinzi, chief or adjuvant herbs in Xiaojiyinzi can reduce the nephrotoxicity of caulis aristolochiae manshuriensis.

Objective To investigate the prevalence of lower urinary tract symptoms in women in a community in Fuzhou. Methods We designed a patient-completed questionnaire according to Bristol Female Lower Urinary Tract Symptoms (BFLUTS) questionnaire.A few parts of the questionnaire were adjusted based on living habits and social backgrounds in our country.The health care workers distributed and collected the questionnaires and instructed the women to fill in them one by one. Results A total of 6066 questionnaires were distributed and 5587 were collected. Of the responders 4745 women were more than 18 years. The prevalence of stress incontinence, urgency incontinence,urgency,frequency and nocturia were 9.0% (425/4745),2.4% (113/4745),10.3% (489/4745),1.5% (72/4745) and 9.8% (446/4745),respectively.The prevalence of storage symptoms increased with age,showing a 20.5%(104/507) in 18~27 years’ group,19.1% (332/1740) in 28~37,22.5%(338/1503) in 38~47,32.2%(202/628) in 48~57,41.2%(61/148) in 58~64,58.0% (127/219) in ≥65 years’ group. The overall prevalence was 24.5%.The prevalence of delayed urinary,intermittent stream,increased abdominal urination, incomplete emptying and voiding pain were 7.0%(330 cases),4.1%(194),4.6% (217),4.9% (233) and 4.8%(229),respectively.The prevalence of general voiding dysfunction increased with age,showing a 13.0% (66/507) in 18~27 years’ group,9.3% (162/1740) in 28~37,10.7%(161/1503) in 38~47,13.2%(83/628) in 48~57,16.2% (24/148) in 58~64 and 26.9%(59/219) in ≥65 years’ group.The overall prevalence was 11.7%. Conclusions The prevalence of lower urinary tract symptoms are high in community-dwelling women,and the prevalence of storage symptoms are more common than that of voiding dysfunction in these women.

Objective To assess clinical efficacy and safety of linezolid in treating postoperative intracranial infec-tion after neurosurgery operation,and provide clinical basis for the treatment of postoperative intracranial infection. Methods From January 2011 to December 2012,clinical data of 51 neurosurgery patients receiving linezolid for trea-ting postoperative intracranial infection were collected,changes in symptoms,temperature,cerebrospinal fluid (CSF)bacterial culture,as well as white blood cell (WBC)count,protein and glucose in CSF before and after therapy were compared,clinical efficacy and safety of linezolid in the treatment of postoperative intracranial infection were assessed based on the diagnostic criteria for intracranial infection.Results After linezolid treatment,30 cases of postoperative intracranial infection were cured,and linezolid was effective in 1 2 cases,improved in 5 cases,and ineffective in 4 cases,total effective rate was 92.16%.Of 47 cases with effective therapy,the mean therapy day were 12.5 d (2-27 d),11 of whom isolated gram-positive bacteria from CSF before therapy,and CSF culture were all negative after linezolid therapy.Conclusion Linezolid is effective for treating intracranial infection caused by Staphylococci,Enterococci and other gram-positive bacteria which failed to response to vancomycin therapy.

Objective To reconstruct caudate nucleus,lentiform nucleus and thalamus three-dimensionally,fuse these neural structures with (patient's) radiological images and provide anatomical data for diagnosis and treatment of neurosurgical diseases. Methods Chinese Virtual Human dataset was segmented using image-transparency method at first and each image was smoothed by eroding and dilating, then fused neural structures with MRI,the neural structures and brain in MRI were reconstructed and displayed using surface rendering and volume rendering lastly. Results The reconstructed neural structures were smooth,natural and realistic.Their shapes and positions was clearly displayed and could be rotated, observed in any direction.On the fused images,the neural structures and tumor could be seen at the same time.Conclusion The reconstructed structures and fused images have great reference value to teaching and learning and diagnosis and treatment of neurosurgical diseases.
