Objective To study the clinical effect and complication of the combination treatment of lamivudine and adeforvir dipivoxil in decompeasated hepatitis B cirrhosis. Methods Eighty-six cases of decompensated hepatitis B cirrhosis were divided into the observation group and the control group with 43 eases each by random digits table. The control group was treated with routine treatment and lamivudine, and the observation group was added with adefovir dipivoxil on the base of the treatment in the control group. The clinical effect after 12 months' treatment was evaluated. Results After 12 months'treatment, the level of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), albumin ( ALB ) and Child-Pugh grade had significant improvement than that before the treatment in two groups(P < 0.05 ), and in the observation group they improved more obvious (P <0.05). The frequence of seroconversion of HBeAg/HBeAb and HBV DNA in the observation group was higher than that in the control group [86.05%(37/43) vs. 65.12%(28/43),79.07% (34/43) vs. 55.81%(24/43)], and the difference between the two groups was significant (P < 0.05 ). Seven cases of times complications happened in the control group and 8 cases of times complications happened in the observation group and the difference between the two groups was not significant (P > 0.05 ). Conclusion The effect of lamivudine and adefovir dipivoxil in the treatment of decompensated hepatitis B cirrhosis is superior to the only lamivudine.

AIM:To investigate the effects of ethane 1,2-dimethanesulfonate (EDS) preconditioning on renal ischemia/reperfusion (I/R) injury in male Sprague-Dawley (SD) rats.METHODS: Male SD rats (n=48) were ran-domly assigned to 6 groups:blank, sham, I/R, EDS+I/R, EDS+testosterone (TST) +I/R, and castration (Cast)+I/R.The renal pedicles were bilaterally occluded with a microvascular clamp for 45 min to establish renal I/R-induced in-jury model.Bilateral orchiectomy was conducted 2 weeks before surgery .EDS (75 mg/kg) was intraperitoneally injected 5 d before operation .Blood samples were collected 24 h after reperfusion from the vena orbitalis posterior plexus .Luteinizing hormone (LH), TST, serum creatinine (SCr), blood urea nitrogen (BUN), and kidney injury molecule-1 (KIM-1) were detected.The renal tissues were harvested to measure the level of TNF-αand the expression of Fas mRNA and caspase-3 protein.RESULTS:Serum TST levels in EDS +I/R group and Cast +I/R group were below the minimum detectable threshold.Compared with other groups , the rats in EDS+I/R group and Cast +I/R group had higher levels of SCr , BUN and KIM-1 (P<0.05).SCr and BUN levels showed no significant difference between EDS +I/R group and Cast +I/R group (P>0.05), but KIM-1 level in EDS+I/R group was lower than that in Cast +I/R group (P<0.05).After reper-fusion for 24 h, the levels of TST and LH in EDS +I/R group, Cast+I/R group and EDS+TST+I/R group were lower than those 1 h before operation (P<0.05).Compared with Cast+I/R and I/R group, the TNF-αlevel and expression of Fas mRNA and caspase-3 protein were significantly decreased in EDS +I/R group ( P<0.05 ) .CONCLUSION: EDS preconditioning substantially reduces the serum TST level , thus attenuating I/R-induced acute renal injury .TNF-α-induced Fas/FasL pathway may be involved in this process .

Objective To explore the migration and differentiation of the human neural stem cells (hNSC) after being transplanted to the neonatal rat lateral ventricle,to provide some data on therapy for neonatal cerebropathy by using of neural stem cells.Methods N2 medium containing EGF+FGF2+LIF was used to culture the NSC spheres from the forebrain tissues of aborted human fetus.The hNSC was identified by detecting the NSC marker nestin antigen and showing the potency to differentiate into neural cells( including astrocytes,oligodendrocytes and neurons)by using indirect immuno-fluorescence assay(IFA).The part of the hNSC in-vitro cultured for 14 d was digested to suspensions of cell.Cultured for 14 d, the hNSC in-vitro and the suspension were transplanted into the lateral ventricles of the neonatal rat brains.The rats were respectively killed at 24,48 and 72 h respectively post-transplant,the whole brain was sectioned,and the special immuno-response detection was performed by using anti-human nuclei(anti-hNuc)and anti-human neurofilament(anti-hNF).Results In vitro culture,the typical NSC spheres were obtained from the forebrain of the human fetus.The suspensions of cells were obtained from the neurosphere.In neurosphere group, the results of anti-hNuc detecting tracing at 72 h post-injection showed that the grafts had migrated into the cortex grand layers of olfactory bulbus,medial precentral area of lobus frontalis,hippocampal,and lobus occipitalis.The label-positive cells lined along the Cerebellar Purkinje cell layers and appeared in most parts of mesencephalons.The immuno-respons results of anti-hNF showed that the positive cells scattered in the grand layer of cortex,the connection among positive cells was watched.In suspensions group,the results of anti-hNuc detecting tracing at 24 h post-injection show a great quantity of positive cells in the ventricles and injection track.At 72 h, a small quantity of positive cells remained in the ventricle and nearby brain tissue.Conclusions Whole neurospheres migrated intensely and differentiated into neurons and gliocytes.At the same time,transplants of cells from suspension transplants showed limited or no migration because of internal environment of the brain and construction of neurospheres.

Reactive oxygen species (ROS) is defined as the electron reduction product of oxygen with high reactivity which can maintain normal physiological functions and redox homeostasis. The tumor microenvironment is in a state of oxidative stress. ROS can affect multiple processes of tumor immune response by modulating the phenotype and functions of tumor cells and immune cells. With the rapid development of immunology, ROS-based tumor immunomodulation has been widely concerned and studied. In this review, the mechanism of ROS participating in tumor immune response is elaborated. Meanwhile, the research process and application of ROS in tumor immunomodulation in recent years are reviewed and analyzed.

Objective To examine the possibility that a candidate causal species of the skin and lung tumor promotion induced by exposure to dimethylarsinic acid(DMAv)and dimethylarsinous acid(DMAⅢ),caused by the induction of oxidative stress in mice.Methods Two stages lung tumotigensis animal model induced by lung tumor initiator(4-nitroquinoline 1-oxide,4NQO)and promoter(DMAv)in ddY mice,was used to examine the effect of(-)epigallocatechin gallate(EGCG)on DMAv promoting lung tumorigenesis.Two stages skin tumorigenesis animal model induced by skin tumor initiator[dimethylbenz(α)anthracene,DMBA]and promoter(DMAⅢ)in hairless mice.was used to examine the effects of DMAⅢ in skin tumorigenesis and histopathology.The goxo-2'-deoxyguanosine (8-oxodG)in lung and epidermis were analyzed by HPLC.Results The incidence of lung tumors and 8-oxodG level of lung tissue decreased significantly in 4NQO+DMAv+EGCG group.compared with 4NQO+DMAv group (0.89±0.30 vs 4.00±0.82,1.21±0.09 vs 1.53±0.32,P＜0.01).The incidence of severe keratosis in DMBA+ DMIⅢ group was more than that in DMBA group(25 vs 10,P＜0.05).An significant elevation of 8-oxodG in epidermis was observed in 0.5 h[(1.67±0.17)/105 dG],1.0 h[(1.62±012)/105 dG],2.0 h[(1.66±023)/105dG], 3.0 h[(1.60±0.15)/105 dG],compared with 0 h[(1.25±0.11)/105 dG],being significant(P＜0.05).Conclusion tumor promotion due to DMAv administration is mediated by DMAⅢ through the induction of oxidative stress.

Objective To investigate the changes of early and delayed washout rates of 99Tcm-methoxyisobutylisonitrile (MIBI) in ischemic heart disease (IHD), and to explore the value of 99Tcm-MIBI SPECT in evaluating impairment of ischemic myocardial cells. Methods Patients diagnosed of IHD with three-vessel stenosis ( ≥50% ) without myocardial infarction based on angiography (CAG) underwent 99Tcm-MIBI static planar and gated SPECT imaging. The early (90 min after the intravenous injection) and delayed (4 h after the intravenous injection) washout rates of 99Tcm-MIBI and left ventricular ejection fraction (LVEF) of IHD patients and normal subjects were compared using t-test. Linear correlation analysis was performed between the early, delayed washout rates and LVEF measured by gated SPECT. Results Statistically significant lower early washout rate of 99Tcm-MIBI was observed in IHD group than control group: (13.44 ± 2.87 )%vs ( 17.32 ± 4.92) %, t = 2.384, P ＜ 0.05, but higher delayed washout rate of 99Tcm-MIBI was observed in IHD group than control group: (19.24 ±4.71)% vs (15.23 ±3.81)%, t= -2.246, P＜0.05. LVEF in IHD group was significantly lower than that in control group: (55.71 ±7.97)% vs (67.75 ±5.43)%, t =-4.418, P ＜0.01. There were no correlations between the early/delayed washout rates and LVEF, respectively in IHD patients (r = -0.212, P ＞ 0.05; r =0.352, P ＞ 0.05, respectively). Conclusion 99Tcm-MIBI washout rate may reflect myocardial cell impairment due to IHD.
