Objective To determine the effect of NS3 and NS4A proteins of Zika virus on the neuronal migration in vivo.Methods To identify the coding sequence of NS3 and NS4A,the genome of Zika SZ01 was sequenced by rapid amplification of cDNA ends (RACE) and reverse-transcription PCR,then NS3 and NS4A was constructed in pCIG vector fused with Flag-tag to express these proteins.And then these plasmids was transfected into the embryo brain of E13.5 mice by in utero electroporation,the distribution of the cells which express these proteins in the cortex was detected by Flag,eGFP and TBR1 fluorescence in E18.5 mice through immunohistochemistry so as to assess the influence of viral proteins on the neuronal migration of mouse cortex.Results 1) Sequence results showed that the amino acid sequence of NS4A is consistent with NCBI data,while NS3 has 1 amino acid mutant.2) As the fluorescence of Flag and eGFP can co-localization,the eGFP fluorescence signal marks the cells that have expressed these virus proteins in cortex.3) TBR1 fluorescence shows the distribution of the cells that express NS4A in vivo are significantly different from pCIG control and NS3 (P＜0.001).Conclusions The NS4A protein of Zika virus may affect the neuronal migration in vivo.

Objective To observe the clinical efficacy of skin needling plus flash cupping for hemifacial spasm. Method Forty patients were randomized into a treatment group and a control group, 20 in each group. For both groups, the following acupoints were selected: Baihui (GV20), Sishencong (EX-HN1), Yifeng (TE17), Xiaguan (ST7), Cuanzhu (BL2), Yangbai (GB14), Taiyang (EX-HN5), Quanliao (SI18), Jiache (ST6), Dicang (ST4), Hegu (LI4), and Waiguan (TE5). Skin needling plus flash cupping was used for the treatment group, while even reducing-reinforcing needling method was used for the control group. Seven-day treatments were considered as a treatment course, and the therapeutic efficacy was analyzed after 3 courses. Result The cure rate was 65.0%in the treatment group versus 45.0% in the control group, and the difference was statistically significant (P<0.05). Conclusion Skin needling plus flash cupping can produce a significant efficacy in treating hemifacial spasm, better than ordinary needling method.

Objective To investigate the association between the presence of cerebral microbleeds and chronic kidney disease in patients with ischemic stroke.Methods Patients with ischemic stroke within 1-6 months were consecutively recruited.Cranial MRI was taken within two weeks after recruitment.Cerebral microbleeds were assessed using Microbleed Anatomical Rating Scale on gradient echo MRI.Demographics including sex,age and risk factors were obtained.Chronic kidney disease was defined and classified according to National Kidney Fundation-Kidney Disease Outcome Quality Initiative Guideline.Glomerular filtration rate (GFR) was estimated by using the abbreviated Modification of Diet in Renal Disease equation.Results Of the 636 patients included,mean age was (59.8 ± 10.1) years,435 (68.4％) were male.Sixty-six had decreased estimated GFR (eGFR; ＜ 60 ml · min-1 · 1.73 m-2).Two hundred and one (31.6％) patients had cerebral microbleeds,which were most commonly located in deep or infratentorial location (133/201,66.2％).The presence of cerebral microbleeds was much higher in patients with decreased eGFR than the others (48.5％ (32/66) vs 29.6％ (169/570),x2 =9.709,P =0.002).Age,history of hypertension and decreased eGFR were associated with the presence of cerebral microbleeds in univariate analysis.In multivariate analysis,decreased eGFR was independently associated with the presence of cerebral microbleeds in deep or infratentorial location (OR =1.457,95％ CI 1.044-2.034,P =0.027),but not associated with the presence of cerebral microbleeds in pure lobe.Conclusion Impaired kidney function is associated with the presence of cerebral microbleeds in deep or infratentorial regions in patients with ischemic stroke.

Objective To investigate the incidence and risk factors of cerebral microbleeds(CMB) in ischemic stroke patients.Methods Patients with cerebral infarction for 1～6 months were recruited.Clinical data were recorded.MRI was reviewed blindly to determine the number of CMB and lacunar infarcts and the white matter lesions(WML).The independent risk factors of CMB were analyzed with the Logistic multivariable regression.Results 636 subjects were included.CMB were found in 250 cases(39.3%).The incidence of CMB in patients of ≤50,50～65 and >65 years old were 27.2%,38.1% and 47.6% respectively(P<0.05).CMB was more frequent in patients with more lacunar infarcts(P<0.05).The incidence of CMB in patients with negative,mild,moderate and severe WML were 21.9%,33.8%,46.9%and 63.1% respectively(P<0.05).Logistic regression analysis showed that history of hypertension(OR=1.523,95% CI 1.019～2.276),severity of WML(OR=1.535,95% CI 1.258～1.874) and lacunar infarcts(OR=1.517,95% CI 1.087～2.118) were the independent risk factors for presence of CMB.Conclusion CMB was frequent in ischemic stroke.The frequency of CMB increased with aging,grade of lacunar infarcts and WML.History of hypertension,severity of WML and lacunar infarcts were the independent risk factors for CMB presence.

Objective To compare two verification tools for intensity modulated radiotherapy (IM-RT) and to investigate the feasibility of a new three dimensitional verification tool. Methods Five patients receiving IMRT were randomly chosen for the quality assurance plans with MapCHECK Model 1175 (SunNu-clear, Melbourne, FL,USA) and Delta4(ScandiDos, Sweden) by using Philips Pinnacle 8.0D treatment planning system. Dose verification was measured with the Varian Clinical 23EX LA. Results The overall average percentages of pass points in DD2% DTA2 mm, DD3% DTA3 mm and DD4% DTA4 mm were 84.7%, 97. 1% and 99.3% with MapCHECK Model 1175, 86.2%, 98.2% and 99.6% with Delta4 re-spectively. The differences were statisticically significant (t = 3.94, P = 0.003 ; t = 3.17, P = 0.011 ; t = 3.05 ,P =0.014,respectively). The gantry angle was changed to zero degree with MapCHECK, but not with Delta. The effects were embodied with Delta, such as the gravity on leaf position accuracy of MLC, the treat-ment table on dose distribution and the earth magnetism on dose system. Conclusion Delta4 is an ideal verification tool for intensity modulated radiotherapy.

Objective To observe whether bone marrow mesenchymal stem cells (MSCs) can promote the repair of IgA nephropathy and to explore its possible mechanism. Methods Sprague-Dawley rats were randomly divided into three groups which were MSCs injection group, normal saline(NS) infusion group and healthy control group. IgA nephropathy model was established by the improving method with BSA +SEB +CCl4 in former two groups. MSCs of SD rats were continuously cultured in vitro and identified with specific surface antigens by flow cytometry and osteogenic and adipogenic differentiation. MSCs were labeled with bromodeoxyuridine (BrdU) in vitro before transplanted. At 1st and 4th week after MSCs injection, the changes of body weight, urine protein, renal function, histopathology and IgA immunofluorescence were observed. MCP-1, TGF-β1 in urine were detected by ELISA. The expression of MCP-1, TGF-β1 in kidney were examined by RT-PCR. The cytokines and BrdU labeled MSCs were detected by immunohistochemistry to observe the disposition in kidney. Results At the end of the first week of MSCs transplantation, MSCs group urine protein (36.86±4.78) mg/24 h, serum creatinine (53.50±6.28) μmol/L, and the NS group urine protein (66.98±5.86) mg/24 h, serum creatinine (82.50±8.36) μmol/L, the differences between two groups were significant (P<0.05). At the same time, the content of MCP-1, TGF-β1 in urine and expression in renal tissue of MSCs group were obviously less than those of NS group (P <0.05). At the end of the 4th week, the body weight, histopatholngy, IgA immunofluorescence of MSCs group were remarkably improved as compared with those of NS group. The content of MCP-1, TGF-β1 in urine and expression in renal tissue, and renal pathological change in MSCs group had no significant differences as compared with those of healthy control group. As the time passed, the disposition of BrdU-labeled MSCs in kidney was taper. Conclusions MSCs injection contributes to renal repair in rat IgA nephropathy. The mechanism may partly depend on adjusting the excretion of cytokines in renal microenvironment and/or other functions rather than completely depend on their differentiation to renal cells.

BACKGROUND; Authors have proposed the hypothesis that, the mechanism change may result in the mismatch between the energy production and energy consumption during the aerobic exercise, and pyruvate can be transformed into lactic acid, which may prevent the accumulation of pyruvate in cytoplasm and in the energy production of glycolysis so as to ensure the fast energy supply in zymolysis; the mechanism of this biochemical event may be the adjustment of energizing velocity via glycomechanism zymolysis.OBJECTIVE: To observe the effect of oxygen inhalation on metabolic transition, study the mechanism of metabolic transition under the lactate threshold intensity in human body and animal, and verify the result consistency between the two.DESIGN: Randomized control observation.SETTING: Department of Physical Education, Hebei Normal University; Department of Physical Education, Langfang Teachers College.PARTICIPANTS: A total of 24 male university students majoring physical education were adopted, weight (58±4) kg,height (175±6) cm, age (21 ±2) years. They were consisted of 12 Level B national athletes and12 common students.Additionally 30 SD male rats were used.METHODS: The experiment was carried out in the Laboratory of Physical and Physiological Function, Department of Physical Education in Hebei Normal University from April to June in 2006. Twenty-four students were recruited to exercise incrementally in ergometer; in addition, thirty SD rats were assigned to swim incrementally, 15 rats in each group. First, the intensities of metabolic transition were determined, then the exercise protocol was repeated on the conditions of inhaling and not inhaling oxygen. For student group, 50 W loading was incremented every 2 minutes, while the rats were added with 1% of their weights until unacceptable. Gradually incremented loading was used to transform the aerobic mechanism to anaerobic mechanism. The vein blood oxygen partial pressure, pyruvate and lactate contents were measured before and during the exercise (lactate threshold intensity) to evidence the reliability and validity of hypothesis.MAIN OUTCOME MEASURES: The vein blood oxygen partial pressure, pyruvate and lactate contents under lactate threshold intensity and oxygen inhaling supplementary.RESULTS: All 24 testees and 30 rats were involved in the result analysis. ①During the gradually incremented exercise,the lactic acid curve obtained at the end of 2-minute loading showed the difference of metabolic transition intensity and training level in accordance with individual lactic acid threshold, which was obviously lower in the trained exercisers.②Under the lactate threshold intensity, the blood lactate was not correlated to the oxygen partial pressure whether in human body or rats and whether inhaling oxygen or not [(3.61±0.56), (5.43±0.55) mmol/L; (4.46±0.86), (7.80±0.27) kPa,r =0.31, 0.31, P ＞ 0.05]; there was significant difference between the blood lactate and pyruvate contents [(1.04±0.16),(0.91±0.37) mmol/L, P ＜ 0.001]. The human body's saturation of blood oxygen was no less than 98% during the entire protocol. ③Under the repeated exercise and lactate threshold intensity, the pyruvate average value was (0.97±0.17),(1.04±0.16) mmol/L; (0.93±0.25), (0.91 ±0.37) mmol/L, respectively. There was no significant difference between the blood pyruvate before the exercise and under the lactate threshold intensity in both human body and animals (P ＞ 0.05).CONCLUSION: There is no hypoxia at the transition from aerobic to anaerobic metabolism. Oxygen inhaling supplementary has no influence on the mechanism transition; It is not easy for the pyruvate to pass the myocyte membrane, but the lactate can. The result demonstrates that the pyruvate can transform to lactate directly, which can also prevent the accumulation of pyruvate in kytoplasm.
