Objective To characterize non-headache symptoms during the migraine attack phase in migraine patients. Methods We enrolled in the present investigation 71 patients with migraine with and without aura who had sought medical treatment in our department from January 2010 to January 2011. We used a self-made migraine questionnaire to investigate associations of the non-headache symptoms with the sociodemographic factors, subtypes, severities and attacks of the headache in the patients. Results There were no significant differences in the number of non-headache symptoms among patients with different ages, genders, education levels, subtypes, severities, mean attack frequencies per month (P＞0.05). The most frequently reported non-headache symptoms were nausea (87.3％),phonophobia (81.7％) and mood change (69.0％).The incidences ofphonophobia,sleep disorder and osmophobia were significantly higher in patients without aura than in patients with aura (P＜0.05).Conclusion Migraine attacks are often accompanied by a variety of non-headache symptoms of which the most frequently reported ones are nausea,phonophobia and mood change.Patients without aura tend to have more phonophobia,sleep disorder and osmophobia than those with aura.

Aim To screen a more suitable transfection recep-tor,and improve the efficiency of constructing cell lines highly expressing human peptide transporters 1 (hPepT1 ).Methods The recombinant plasmid pcDNA3.1 (+)-hPepT1 was transfect-ed into MDCK cells and HeLa cells by LipofectamineTM 2000 transfection reagent,respectively.The monoclonal cells were se-lected and cultured.Expression of hPepT1 mRNA and protein were determined by qRT-PCR and Western blot,respectively. The uptake capacity of Glysar in transfected cells was examined. Results Compared with wild type cells,the expression of hPepT1 and the uptake of Glysar in transfected MDCK cells and HeLa cells significantly increased (P <0.05).Although the up-take of Glysar in HeLa cells was higher than that of MDCK cells,on the contrary,the expression of hPepT1 and the uptake of Glysar in MDCK-hPepT1 cells was higher than that of HeLa-hPepT1 cells.Conclusion MDCK cells may serve as a more suitable transfected receptor for the construction of a cellular model with high expression of hPepT1 ,which would make the construction of a cell model highly expressing hPepT1 more effi-cient.

Abstrate:Aim To construct HEK293 cell line with stable and high expression of sodium taurocholate cotransporting polypeptide (NTCP ) efficiently and rapidly.Method Vector expressing EGFP-NTCP fusion protein was constructed and verified by DNA sequencing.The pEGFP-NTCP expression vector was transfected into HEK293 cells by FuGENE 6 transfection reagent. The transfected cells with high expression of green fluorescent protein were selected using fluorescence microscope for screening of G418 for 14 days to obtain cell lines stably and highly expressing NTCP.NTCP expression was detected by RT-PCR,qRT-PCR, Western-blot and the uptake experiment of taurocholic acid.Re-sult RT-PCR,qRT-PCR,Western-blot and the uptake experi-ment revealed that compared to the control cells,the expression of NTCP was significantly positive (P<0.01)in stable trans-fected cells showing green fluorescence (P<0.05 ).Conclusion The HEK293 cell line with stable and high expression of NTCP has been established efficiently and rapidly,which provides a cellular model for the study of the mechanism of the uptake of bile acid derivatives.

Objective To investigate the neurotoxic effects of different concentrations of tetracaine and ropivacaine on the brachial plexus nerve in rats.Methods Forty-eight male Sprague-Dawley rats,weighing 410-430 g,were randomly divided into 8 groups (n =6 each):normal saline group (group NS),0.25％,0.50％ and 1.00％ tetracaine groups (groups T1-3 ),and 0.25％,0.50％,1.00％ and 2.00％ ropivacaine groups (groups R1-4 ).The rats received injection of normal saline 1.0 ml,0.25％,0.50％ and 1.00％ tetracaine 0.5 ml,0.25％,0.50％,and 1.00％ ropivacaine 1.0 ml and 2.00％ ropivacaine 0.5 ml in groups NS,T1-3 and R1-4 respectively through one side of the axillary sheath.The other side of the axillary sheath served as control side.Five days later,compound action potential and nerve conduction velocity (NCV) of the brachial plexus nerve were measured.Tne brachial plexus nerve was obtained as the specimen for microscopic examination with light and transmission electron microscope.Results Compared with the control side and group NS,the compound action potential and NCV of the brachial plexus nerve were significantly decreased in groups T2,3 and R3,4 ( P ＜ 0.05 ).The compound action potential and NCV of the brachial plexus nerve were gradually decreased with the increasing concentrations of tetracaine in groups T1 3 ( P ＜ 0.05 ).The compound action potential and NCV of the brachial plexus nerve were significantly decreased in group R4 as compared with groups R1-3 (P ＜ 0.05).The microscopic examination showed that the pathologic changes were more severe in groups T2,3 and R3,4 than those on the control side and than in group NS.Conclusion 0.50％ and 1.00％ tetracaine,and 1.00％ and 2.00％ ropivacaine can result in pathologic damage to the brachial plexus nerve in rats and the degree of damage is related to the concentration.

OBJECTIVETo study the effect of Wenyang Decoction (WD) on the differentiation of CD34+ progenitor cells of occupational asthma (OA) model rats.

METHODSFifty healthy male SD rats were randomly divided into five groups, i.e., the model group, the blank control group,the WD group,the Western medicine group,the combined group, 10 in each group. Prednisone suspension (10 mg/kg) was administered to rats in the Western medicine group by gastrogavage. WD (20 g/kg) was administered to rats in the WD group by gastrogavage. Prednisone suspension plus WD was administered to rats in the combined group by gastrogavage. Normal saline was administered to rats in the model group and the blank control group by gastrogavage. The general condition of rats was observed. Expression levels of peripheral blood IL-5 and eotaxin, eosinophils (EOS), CD34+, CC chemokine receptor 3 (CCR3+) in bone marrow suspension were detected by ELISA, Wirght-Giemsa, and flow cytometry, respectively.

RESULTSCompared with the blank control group,expression levels of IL-5 and eotaxin in peripheral blood were significantly higher (P < 0.01), and the count of EOS and CD34+ cells, as well as CD34+ /CCR3+ significantly increased (P < 0.01) in the model group. Compared with the model group, expression levels of IL-5 and eotaxin, the count of EOS, CD34+ cells, CD34+ / CCR3+ were lowered in three treated groups (P < 0.01). Compared with the Western medicine group, the count of EOS and CD34+ / CCR3+ decreased in the combined group (P < 0.01). The count of EOS was significantly lower in the combined group than in the WD group (P < 0.01).

CONCLUSIONWD could reduce levels of in vivo inflammatory factors, and restrain the differentiation and recruitment of EOS,thereby alleviating the differentiation of CD34 progenitor cells to EOS.

Objective To discuss the value of vivo proton MR spectroscopy,perfusion and diffusion imaging in grading of diffuse astrocytomas.Methods One hundred fifty-four cases with diffuse astrocytomas proved pathologically were collected.35 cases with diffuse astrocytomas including 8 astrocytomas(WHO grade Ⅱ),13 anaplastic astroeytomas(grade Ⅲ)and 14 glioblastoma muhiforms (grade Ⅳ)underwent MR spectroscopy.The Cho/Cr,NAA/Cr and Lac/Cr of three groups in 35 cases were compared.The other 76 cases including 36 low-grade glial tumors(grade Ⅱ),20 anaplastic glial tumors (grade Ⅲ)and 20 glioblastoma multiforms(grade Ⅳ)underwent conventional MR imaging and dynamic contrast-enhanced perfusion MR imaging before surgical resection or stereotactic biopsy,the characteristics of the curve and the value of the maximum relative regional cerebral volume(rrCBV)in the diffuse astrocytomas with various grades were analysed.Fourty-three cases of diffuse astrocytomas including 26 astrocytomas(grade Ⅱ),6 anaplastic astrocytomas(grade Ⅲ)and 11 glioblastoma multiformes (grade Ⅳ)underwent diffusion MRI and the apparent diffusion coefficient rate(ADCR)were compared. Results The Cho/Cr of diffuse astrocytomas in three grades were 2.709?1.228,5.812?2.374 and 5.289?1.462 respectively.There were statistically significant differences between astrocytomas and anaplastic astrocytomas,astrocytomas and glioblastoma multiformes for Cho/Cr(P0.05).The Lac/Cr of diffuse astrocytomas in three groups were 0.100?0.083,1.879?1.595 and 3.656? 2.195 respectively,the differences among three groups were all significant(P0.05).The maximum rrCBV values of glial tumors with Ⅱ,Ⅲ and Ⅳ grade were 1.379?0.739,2.654?1.072,3.218?1.565 respectively and the differences among them were statistically significant(P

Objective To observe the hemodynamic changes of acute after cardiac resynchronization therapy(CRT) interruption in patients with chronic heart failure (CHF),and explore the benefit of hemodynamic of the reverse remodeling and non-reverse remodeling CHF patients during CRT.Methods 46 CHF patients who had undergone implantation of CRT device for more than 6 months were enrolled in the study.The reverse remodeling and non-reverse remodeling were identified by reduction of LV end-systolic volumes ≥ 15％.The two groups underwent echocardiography,and mitral regurgitation area (MRA),velocity time integral of aortic valve (VTI-AV),velocity time integral of mitral valve(VTI-MV),maximum rising rate of left intra-ventricular pressure(+ dp/dtmax),LVFT/T were measured in on and off mode of CRT.Hemodynamic indicators of two groups were compared in CRT on and off modes.The rate of changes of above mentioned parameters ΔMRA,ΔVTI-AV,ΔVTI-MV,Δdp/dt and ΔLVFT/T were calculated and compared in the two groups.Results MRA had significant increasing in both group after 10 minutes intereuption of CRT (P ＜0.01).Two groups had significant worsening of VTI-AV,VTI-AV,+ dp/dtmax and LVFT/T after 10 minutes interruption of CRT as compared to CRT-on mode (P ＜0.05).ΔMRA,ΔVTI-MV,Δdp/dt of reverse remodeling group significantly higher than non-reverse remodeling group(P ＜0.05).But there was no difference in ΔVTI-AV and ΔLVFT/T(P ＞0.05).Conclusions The hemodynamic index become worsening after 10 minutes interruption of CRT in both group of medium-and long-term CRT patients especially in reverse remodeling group,suggesting that patients of both groups have obtained hemodynamic benefits continuously during CRT.Reverse remodeling group get more benefits than non reverse remodeling group.

OBJECTIVETo investigate the therapeutic efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children with chronic myelogenous leukemia (CML), and to analyze the possible prognostic factors.

METHODSThe clinical data of 20 children with CML who had received allo-HSCT was analyzed retrospectively to investigate possible prognostic factors, including age, sex, interval between diagnosis and transplantation, HLA matching between donors and recipients, illness status on transplantation and acute and chronic graft-versus-host disease (GVHD).

RESULTSAt the end of follow-up, 13 of the 20 treated children had disease-free survival (DFS) and the rest (7 cases) died. Four died of severe acute GVHD, two of chronic GVHD and its complications, and one of relapse after transplantation. The three-year DFS was (64.6±1.1%). As shown by the univariate analysis, age was the most important prognostic factor in children with CML who had received allo-HSCT (P<0.05), and in children over 10 years, the prognosis was poor. No other of the above factors had a significant impact on prognosis (P>0.05). The multivariate logistic regression analysis also confirmed age as the only prognostic factor (P<0.01). Severe acute and/or chronic GVHD was the most important cause of patient death. 10/10 HLA-matched donors could improve the transplantation outcome.

CONCLUSIONSAllo-HSCT is an effective treatment for children with CML. To improve the prognosis and treatment outcome, children with CML aged over 10 years should receive allo-HSCT as early as possible. 10/10 HLA-matched donors are preferred in allo-HSCT and GVHD should be prevented.

BACKGROUNDVasoactive drugs are often necessary for reversing hypotension in patients with severe infection. The standard for evaluating effects of vasoactive drugs should not only be based on the increase of arterial blood pressure, but also on the blood flow perfusion of internal organs. The effects of dopamine and metaraminol on the renal function of the patients with septic shock were investigated retrospectively in this study.

METHODSNinety-eight patients with septic shock were divided into three groups according to the highest infusing rate of metaraminol, with the lightest infusing rate of (0.1 - 0.5, 0.6 - 1.0, > 1.0) microgxkg(-1)xmin(-1) in group A, B and C respectively. Urine output, mean arterial blood pressure (MAP), heart rate (HR), urine output, blood urea nitrogen (BUN), creatinine (CRE), urine albumin (U-ALB), urine beta(2)-microglubulin (Ubeta(2)-MG) and Apache III scores were recorded.

RESULTSBefore antishock therapy, hypotension, tachycardia and oliguria occurred to all the 98 patients with septic shock and CRE, BUN, U-ALB, Ubeta(2)-MG and Apache III scoring were abnormal in most cases. With the antishock therapy, MAP, HR, urine output, BUN and CRE in all patients returned gradually to normal (P < 0.05 or < 0.01 compared to those before antishock therapy). U-ALB, Ubeta(2)-MG output and Apache III scoring also reverted but remained abnormal (P < 0.01 compared to those before antishock therapy). No statistically significant differences in the changes of these indices with the time existed among the three groups (P > 0.05).

CONCLUSIONDopamine and metaraminol when applied to the patients with septic shock could effectively maintain the circulatory stability and promote restoration of renal function.
