12 months, baseline serum HBV DNA ≥104copies/ml) were prospectively followed. Virological and serologic responses and laboratory data of liver and renal function of each patient enrolled were monitored every three months. Entecavir resistant mutations were detected by direct sequencing of HBV reverse transcriptase region which was amplified by semi-nested polymerase chain reaction (PCR). HBV sequences of different genotypes obtained from GenBank were aligned to identify entecavir drug resistant substitutions. Results Of the 41 lamivudine refractory CHB patients who met the inclusion criteria, 16 patients (39%) achieved the point of undetectability in HBV DNA level (

Objective To explore the effects of donor dendritic cells(DC)treated with Ad-IL- 12p35siRNA on the survival of allogragft recipients.Methods The recombinant adenoviral vectors carrying IL-12p35siRNA and HKsiRNA were transfected into bone marrow derived DC of BALB/C murine.C57BL/6 recipients were infused with DG(Ad-IL-12p35siRNA DC,Ad-HKsiRNA DC and control DC)from BALB/C donors 7 days before cardiac allograft,the survival time of murine and the change of T_H 1 and T_H2(IL-2,IL-4,IL-10 and IFN-?)cytokine were observed.Results The survival time of p35 group(20.17?2.71)days was longer than that of control group(7.81?1.61)days and HK group(7.17?1.60)days.The concentration of IL-2 and IFN-?in p35 group were significantly lower than those of control group and HK group,otherwise were the concentration of IL-4 and IL-10. Conclusion Pretreatment of dondor dendritic ceils with Ad-IL-12p35siRNA could prolonged cardiac allograft survival in recipicents.

Objective To explore the effect of circadian rhythm disorder on cognitive decline and neurologic impairment after traumatic brain injury (TBI) in rats.Methods Rats were subjected to a weight-drop model of TBI,then the rat models were divided into 2 groups ac-cording to the environmental length of day and night ,namely,the whole day group (12 h light/12 h light) and the control group (12 h light/12 h dark).After 14 days,the Morris water maze test and step-down test were carried out to evaluate the memory of the rats in each group . HE staining and immunohistochemistry ( BrdU, Ki-67) were carried out to evaluate the degree of the neurologic impairment of the rats in each group.And the mRNA expressions of Caspase-3,Caspase-9,Bcl-2 and Bax were evaluated with realtime PCR .Results The memory function of the rats in whole day group was significant lower than control group ;the damage degree of the cells in the hippocampus and the cortical lesion volume in whole day group were significant higher than control group ;the cell proliferation rate and newborn cell survival rate in the whole day group decreased significantly compared with the control group ;the mRNA expression of Bcl-2 in whole day group was signifi-ant lower than control group ,and the mRNA expression of Caspase-3,Caspase-9 and Bax in whole day group was signifiant higher than control group.Conclusion Circadian rhythm disorder can worsen TBI-induced cognitive decline and neurologic impairment .

Objective To study the effect of IGF-1 gene therapy and electric stimulation therapy on the rat models of postpartum stress urinary incontinence, and explore the ideal treatment for this disease.Methods 240 SD female rats were used to establish the model of postpartum stress urinary incontinence by water sac vaginal dilation.148 model rats were randomly selected from 185 successful models and divided into 5 groups:IGF-1 gene therapy, clenbuterol treatment, electric stimulation therapy, injection of empty vector plasmid, and untreated groups.Besides, 20 non-modeled rats were used as blank control group.Urodynamic test was performed, pelvic floor pubococcygeus muscle/muscle weight ratio was calculated, and serum biochemical indices (LDH, CK) were detected, and the morphological changes of pubococcygeus muscle fibers were observed by light microscopy at 1, 21, 42 and 63 days after treatment.Results At 21 days after treat-ment, the maximum bladder capacity, leak point pressure, the contractile force/muscle weight ratio in the IGF-1 group and electric stimulation treatment group were significantly better (P>0.05), and the differences between the IGF-1 group and electric stimulation group were not significant ( P>0.05 ) .Conclusions The effect of IGF-1 gene therapy and electric stimulation on the rat models of postpartum stress urinary incontinence is better than that in the drug therapy group and oth-er groups.

AIM:To establish a rat hyperlipidemia model for studying the aortic expression of heat shock protein 22 (HSP22), tumor necrosis factor alpha (TNF-α) and endothelial nitric oxide synthase (eNOS) and the effect of atorvasta-tin intervention.METHODS:Hyperlipidemia model was established in SD rats.Afterwards, the rats were divided into nor-mal control group, high fat group and high fat+atorvastatin intervention group.The expression of HSP22 and TNF-αin the rat aortas was detected by immunohistochemical assay and the expression of eNOS was assessed by Western blotting.RE-SULTS:No detectable expression of HSP22 and TNF-αin the normal control group was observed.However, the expression of HSP22 and TNF-αwas positive in the high fat group and the atorvastatin intervention group.The mean densities of HSP22 and TNF-αpositive particles were significant lower in the atorvastatin intervention group as compared with high fat group ( both P<0.05) .The expression of eNOS protein in the high fat group and atorvastatin intervention group was significantly lower than that in normal control group (P<0.01).However, no marked difference of eNOS protein expression between high fat group and atorvastatins intervention group was observed.CONCLUSION:The expression of HSP22 and TNF-αin the rat aortas is increased in the hyperlipidemia rat model.This effect can be restored by atorvastatin treatment.The expression of eNOS in the rat aortas is decreased in the hyperlipidemia rat model, but this tendency could not be attenuated by atorvastatin.

Objective To analyze clinical and radiological characteristics in 5 cases of neuromyelitisoptica (NMO) with tumefactive-like demyelinating lesions (TDLs).Methods Five NMO patients with TDLs hospitalized during November 2007 and March 2012 were retrospectively analyzed for clinical and magnetic resonance imaging (MRI) features,as well as therapeutic efficiency and prognoses.Results The male-to-female ratio is 1∶4 and the range of onset ages is 15-44 years old.The median time when TDLs was developed was 36 months after the onset of NMO.The anti-aquaporin 4 was seropositive in all NMO patients with TDLs.Four patients had clinical manifestations of encephalopathy symptoms including coma (n =2),seizures (n =1),narcolepsy (n =1),homonymous hemianopia (n =1).All TDLs grew unilaterally.Two TDLs were located at parietal-occipital,1 at parietal,I at the cerebellum and 1 at the temporal.On MRI,there was no enhanced signal in 4 TDLs,and there was open-ring-like enhanced signals in 1 case.Three TDLs revealed mixed signals intensities on diffusion-weighted images and an increase in the apparent diffusion coeficient values.On the subsequent MRIs,the sizes of 5 TDLs were markedly reduced in 3 cases,disappeared in 1 and another 1 case remained the same.Meanwhile,3 lesions subsequently developed cavity forming.Five cases improved after treatment of high-dose corticosteroid and intravenous immune globulin.Conclusions TDLs is not uncommon in NMO.Encephalopathysymptoms are more frequently affected in NMO with TDLs.TDLs often accompany with extensive vasogenic edema,but without enhancement in acute stage.NMO-IgG antibody testing and brain MRI are important in the diagnosis of TDLs.The therapy of corticosteroid and intravenous immune globulin is recommended.
