The total product of L-lactic acid reached 135g/L besides the rate of glucose consumed and the average L-lactic acid productivity were up to 95% and 2.25g/(L?h) respectively.

OBJECTIVETo explore the cytotoxic responses of spleen T lymphocytes (CTL) in BALB/c mice induced by recombinant HSP110-HER2/neu ICD complex.

METHODSTumor-bearing mouse model was immunized by HSP110-HER2/neu ICD complex. The IFN-γ level secreted by activated spleen T lymphocytes was detected by enzyme linked immunospot assay (ELISPOT). The corresponding CTL activity was measured by granzyme release assay.

RESULTSThe BALB/c mouse model of human mammary tumor highly expressing HER2/neu was established. HSP110-HER2/neu ICD complex immunization led to a significantly higher level of INF-γ than that in HSP110-P(789-797) immunized and HER2/neu ICD immunized mice. HSP110-HER2/neu ICD complex immunized animals also show significant CTL activity. The results of immunohistochemical staining showed that the number of blue spots in the PBS group was 4.57 ± 1.33, HSP110 group 6.83 ± 2.08, HER2/neu ICD group 16.17 ± 2.86, HSP110-P(789-797) group 43.67 ± 4.78, and SP110-HER2/neu ICD group 76.51 ± 8.17. The number of IFN-γ-secreting spleen lymphocytes in the HSP110-HER2/neu ICD group was significantly higher than that in the HSP110-P(789-797) group, and that of HSP110-P(789-797) group was significantly higher than that of HER2/neu ICD group (P < 0.01). The target cell-killing rate of the PBS group was (8.15 ± 1.27)%, HSP110 group (9.51 ± 1.51)%, HER2/neu ICD group (14.03 ± 2.45)%, HSP110-P(789-797) group (25.99 ± 3.04)% and HSP110-HER2/neu ICD group (38.15 ± 3.95)% (all P < 0.01).

CONCLUSIONSHSP110-HER2/neu ICD complex can promote the proliferation and maturation of T lymphocytes into CTLs, and might be used as anti-tumor vaccine to induce potent cytotoxic T lymophocyte immunoresponse against specific tumor cells.

Objective To respectively analyze the patterns and possible predictors of recurrent strokes among patients with initial ischemic stroke.Methods Three hundred and sixty-one patients with recurrent strokes (acute ischemic stroke or intracerebral hemorrhage) after initial ischemic strokes were collected from Jan 2004 to Dec 2009.The data about conventional risk factors such as smoking,heavy alcohol drinking,hypertension,diabetes,hyperlipidemia,heart diseases,head trauma,migraine,family history of cardiovascular disease,and the use of preventive medications were collected and analyzed among patients with different types of recurrent strokes.Results Patients (n =361) were divided into ischemic stroke group (n =321) and hemorrhagic stroke group (n =40) according to the recurrent stroke type.The ischemic stroke group was further divided into the anterior circulation stroke subgroup (n =234),the posterior circulation stroke subgroup (n =75) and watershed cerebral infarction or multiple infarction subgroup (n =12).Multivariate logistic regression analysis revealed that older age at initial stroke onset (OR =1.036,95 ％ CI 1.006-1.067,P =0.02) and hyperlipidemia (OR =2.253,95 ％ CI 1.092-4.647,P =0.028) were both the independent risk factors for the recurrent ischemic stroke.Comparing the subgroups,multivariate logistic regression analysis showed that atrial fibrillation (OR =4.217,95％ CI 1.489-11.942,P =0.007) was the independent risk factor for the recurrent ischemic stroke in the posterior circulation territory.Conclusion Aging and hyperlipidemia are possible predictors of recurrent ischemic stroke after the initial ischemic stroke which would be useful for individualized secondary prevention of stroke.

Objectives To identify the prevalence and risk factors that were associated with poststroke cognitive impairment(PSCI)among a large cohort of consecutive ischemic stroke patients.Methods 526 consecutive patients.who had suffered from ischemic stroke 3 months ago were recruited in this study. Patients were classified as having no cognitive impairment(NCI),cognitive impairment but no dementia (CIND)and vascular dementia(VaD)according to their cognitive function.They were also categorized as with subcortical ischemic vascular diseases(SIVD)or cortical ischemic vascular diseases(CIVD)with neuroimaging findings.Their demographic data.vascular risk factors and stroke characteristics were also dacumented.Results The overall prevalence of PSCI(CIND+VaD)Was 36.7%.Compared with the NCI subjects.PSCI SObjects were older,more dominant femininely,less educated,with more cases of right hemi-paralysis and higher depression scores.but did not have more specific vascular risk factor.Separately,VaD patients demonstrated lower economic level,less spouse-caring,more prevalence of dysphasia,hisher rate of incontinence and more cases with CIVD.while CIND patients had more cases with SIVD.The VaD patients had more cortical lesions and lower depression scores than the CIND patients.On logistic regression analysis,older age,female gender,lower economic level,dysphasia,SIVD,CIVD and hisher depression scores were independent risk factors for PSCI.ConclusionPSCI is common among ischemic stroke patients and related to demographic factors.stroke types,and depression.

Objective To evaluate the efficacy of donepezil for post-stroke aphasia. Methods Sixty patients with acute post-stroke aphasia were divided into treatment group and a control group. All patients had been treated for secondary prevention according to the guideline. The treatment group received donepezil hydrochloride (5 mg/d) for 12 weeks. The efficacy of treatment was measured by comparing the changes of scores of Western Aphasia Battery ( WAB) between baseline and 12 weeks later. Results Compared with the baseline, the changes of scores of all items of WAB and Aphasia Quotient ( AQ) in both group after 12 weeks follow-up were great, however, the change of AQ was significantly greater in donepezil group (34. 14 ± 17. 70) than that in control group (20. 69± 17. 26) (P =0. 004). The patients in donepezil group also showed significant recovery in spontaneous speech, comprehension, repetition, and naming than those in control group (P <0. 05 ). The rate of significant improving in donepezil group was 60. 0% which was significantly greater than that in control group ( 26. 7% ) ( P = 0. 009 ). Conclusion There are spontaneous recovery of post-stroke aphasia within 3 months. Donepezil may facilitate the recovery in spontaneous speech, comprehension,repetition,and naming functions.

Objective To investigate the therapeutic effect of acupuncture and moxibustion on allergic rhinitis and its influence on the patients' quality of life. Method Seventy-two patients with allergic rhinitis were allocated, according to different protocols, to control and observation groups, 36 cases each. The control group received conventional Western drug treatment and the observation group, acupuncture and moxibustion. Both groups were treated for three consecutive months. The effects were evaluated after the completion of treatment. VCAM-1, interleukin-4 (IL-4), interleukin-6 (IL-6) and interleukin-10 (IL-10) levels were measured using enzyme linked immunosorbent assay. The quality of life was assessed using the WHOQOL-BREF. The clinical therapeutic effects and the influences on the patients' quality of life were compared between the two groups. Result The total efficacy rate was 97.2％ in the observation group, which was higher than 86.1％ in the control group (P<0.05). There were no statistically significant pre-treatment differences in VCAM-1, IL-4, IL-6 and IL-10 levels between the two groups (P>0.05). After treatment, VCAM-1, IL-4, IL-6 and IL-10 levels decreased in both observation and control groups compared with before (P<0.05) and were lower in the observation group than in the control group (P<0.05). After treatment, the physical health, psychological health, social relationships, environment and independent ability scores increased in both observation and control groups compared with before (P<0.05) and were higher in the observation group than in the control group (P<0.05). Conclusion Acupuncture and moxibustion has a definite therapeutic effect on allergic rhinitis. It can reduce the levels of inflammatory factors and improve the patients' quality of life.

Objective To observe the effect of obstructive sleep apnea hypopnea syndrome (OSAHS) on the renal function in patients with type 2 diabetes mellitus (T2DM).Methods Sleep apnea hypopnea index (AHI), oxygen desaturation index (ODI), and nighttime lowest oxygen saturation (LSaO2) were evaluated in 298 patients with T2DM using a portable sleep apnea monitor.Patients were divided into T2DM without OSAHS group (n=120) and with OSAHS group (n=178) according to AHI<5.Patients were divided into 3 groups according to estimated glomerular filtration rate (eGFR): eGFR>90 ml·min-1·(1.73 m2)-1 (n=190), 90>eGFR>60 ml·min-1·(1.73 m2)-1 (n=84), eGFR<60 ml·min-1·(1.73 m2)-1 (n=24).The influencing factors of eGFR and AHI were analyzed by logistic regression analysis.Results There were significant differences in eGFR, uric acid (UA), high density lipoprotein-cholesterol (HDL-C), waist circumference, hip circumference, body mass index (BMI), and urinary albumin between T2DM without OSAHS and with OSAHS groups(all P<0.05).eGFR showed a significant correlation with AHI(r=-0.154, P=0.008), ODI(r=-0.236,P<0.01),and LSaO2(r=0.145, P=0.024).Logistic regression revealed that eGFR(OR=0.991, 95%CI 0.983~0.998, P=0.014), BMI(OR=1.107, 95%CI 1.028~1.193, P=0.008)were independent risk factors for AHI.There were significant differences in age, urinary albumin, AHI, ODI, LSaO2 among groups with various eGFR levels (P<0.05).Stepwise regression showed that age(β=-0.456, 95%CI-0.571~-0.346,P<0.01)and AHI(β=-0.119, 95%CI-0.226~-0.007,P=0.037) were independent risk factors for eGFR.Conclusions OSAHS is a risk factor for renal impairment in patients with T2DM.
