Post-hepatitis cirrhosis (PHC),which results from either hepatitis B virus (HBV) or hepatitis C virus (HCV) infection,and its associated with hemodynamic changes may cause the spleen to become functionally hyperactive-a condition known as hypersplenism.Hypersplenism is associated with anemia,leukopenia,thrombocytopenia and splenomegaly.There are several effective methods to treat hypersplenism with the development of medical technology and the main purpose is the remission of hypersplenism,reducing the portal hypertension and decreasing the risk of hemorrhage.However,complete splenectomy or partial treatment of the hyperactive spleen is still controversial all over the world.This may be caused by the lack of the knowledge on the pathophysiological characteristics and clinical significance of treating hypersplenism.This review is a comprehensive discussion on the recent research which investigates hypersplenism caused by PHC.

To study the mechanism of human chronic renal allograft rejection, kidney tissues were taken from 16 patients with chronic renal allograft rejection and from 5 healthy subjects, and underwent the frazed section staining for ICAM-1 and VCAM-1 to anti-ICAM-1 and anti-VCAM-1 respectively by using immunohistochemistry(ABC).The results showed that there were differ-ent distribution of ICAM-1 and VCAM-1 expression in nomal kidney and renal allograft during chronic rejection.It was suggested that ICAM-1 and VCAM-1 might play an important role in the pathogenesis of human chronic renal allograft rejection.

Objective To explore the relationship between diet intake and diabetes mellitus(DM) and impaired fasting glucose (IFG) in adult residents in Guangxi,so as to provide scientific basis for dietary prevention.Methods 2 281 people(1 020 from urban areas and 1 261 from rural areas) aged 18 years and above were selected from 4 cities and 4 countrysides in Guangxi through a multistage stratified random sampling.The investigation included the meal investigation,medical examination and blood assay. Results Total 37 people(26 from urban and 11 from rural) suffered from DM and 26 people(15 from urban and 11 from rural) had IFG,the general prevalence rate of Impaired Glucose Metabolism(IGM) was 2.8%(4.0% for urban and 1.7% for rural);It showed that the prevalence of IGM in city was obviously higher than that in the countryside(P

Abstract: The activities of four CYP450 enzymes (CYP3A, 1A2, 2El and 2C) and the mRNA expression levels of CYP1A2, 2El, 2Cll and 3A1 in rat liver were determined after Wistar rats were orally administered with brucine (BR) at three dosage levels (3, 15 and 60 mg.kg-1 per day) and the high dose of BR combined with glycyrrhetinic acid (GA, 25 mg.kg-1 per day) or liquiritin (LQ, 20 mg.kg-1 per day) for 7 consecutive days. Compared with the control, brucine caused 24.5% and 34.6% decrease of CYP3A-associated testosterone 6beta-hydroxylation (6betaTesto-OH) and CYP2C-associated tolbutamide hydroxylation (Tol-OH), respectively, and 146.1% increase of CYP2El-associated para-nitrophenol hydroxylation (PNP-OH) at the high dose level. On the other hand, (BR+GA) caused 51.4% and 33.5% decrease, respectively, of CYP2El-associated PNP-OH and CYP1A2-associated ethoxyresorufin-O-de-ethylation (EROD) as compared with the high dose of BR group. Meanwhile, (BR+LQ) caused 41.1% decrease of CYP2El-associated PNP-OH and 37.7% increase of CYP2C-associated Tol-OH. The results indicated that the co-administration of BR with GA or LQ had effect on mRNA expression and activities of the CYP450 enzymes mentioned above to some extent, and the in vivo antagonism of LQ on BR-induced CYPs adverse effects and the in vivo inhibitory action of GA on CYP2E1 and 1A2 might play an important role in the detoxification of Radix Glycyrrhizae against Strychnos nux-vomica L.

Objective To investigate regeneration and repair effect after ChABC,GDNF and Nogo-A Ab combination treatment for experimental spinal cord injury model.Methods Rat (T7-8 )complete spinal cord injury crosscutting animal model was established.The SD rats were randomly divided into 6 groups:normal group, sham operation group,simple transection group,A (ChABC)group,G (GDNF)group,N (Nogo-A antibody) group,and AGN (ChABC+GDNF+Nogo-A antibody)group.At 24 w after spinal cord injury,BDA tracer,NF-200,GAP-43,and GFAP immunohistochemistry were evaluated.Results BDA tracer of A group,G group and N group showed dye light,the proximal end of damaged zone showed the blue tracer particles,while damaged zone showed few blue regenerated nerve fibers.AGN group showed visible blue nerve fibers through the damaged zone and the distal segment in the damaged zone;the central zone of injury vacuolar degeneration showed the blue dyed fibers.NF-200 immunohistochemical staining showed NF-positive staining in A group,AGN was stronger than that in control group and simple transection group (P <0.05),AGN group than G group,N group significantly increased (P <0.05).GAP-43 positive staining in A group and AGN treatment group was stronger than in control group and simple transection group (P <0.05),AGN group significantly increased compared with A,G and N groups (P <0.05).GFAP positive staining in control group and simple transection group was stronger than in each treatment group (P <0.05),but A group,G group,N group and AGN group showed no significant differences (P > 0.05 ).SEP wave was detected in control group and AGN group,while the latency time was longer in AGN group than in control group.Conclusion ChABC,GDNF,and anti-Nogo-A antibody used alone or in combination can improve spinal cord injury and nerve cell function,and the joint application could improve regeneration after spinal cord injury than any monotherapy.

Objective To observe the activation of anti-viral innate immune response of type Ⅰinterferon and inhibition of hepatitis B virus (HBV)genome replication in mice by HBV-3p-siRNA. Methods HBV-3p-siRNA was designed by targeting specific sequence of HBV S/P mRNA and was generated by in vitro transcription.Negative control siRNA (NC-siRNA)and non-modified HBV-siRNA were used as control groups.Blood samples were collected from tail vein of mice and the model of HBV-infected mice were established by hydrodynamic injection.Forty mice were divided into 4 groups with 10 in each group.The model group was only injected with pGL3.0-HBV1 .2 copy plasmid.The negative control group received peritoneal injection of NC-siRNA.HBV-siRNA group received peritoneal injection of HBV-siRNA and HBV-3p-siRNA group received peritoneal injection of HBV-3p-siRNA.The interferon-β(IFN-β)and hepatitis B surface antigen (HBsAg)in serum were detected by enzyme linked immunosorbent assay (ELISA).The copies of HBV DNA were assessed by fluore scence quantitative polymerase chain reaction (PCR ).The statistical difference between groups was determined using One way-ANOVA analysis by LSD or Dunnett T3.Results Serum level of IFN-β was (12.37±5 .32)pg/mL in model group,(22.61 ±6.29 )pg/mL in negative control group,(26.40±5 .39)pg/mL in HBV-siRNA group and (68.37± 21 .00 ) pg/mL in HBV-3p-siRNA group.The secretions of IFN-β into serum were significantly enhanced by HBV-siRNA and HBV-3p-siRNA compared with model group (F =23.988 and 46.523,respectively,both P <0.01).Serum level of HBsAg was (2 864.86±907.11 )ng/mL in model group,(2 198.86±456.89 )ng/mL in negative control group,(1 049.71 ± 396.28 )ng/mL in HBV-siRNA group and (640.86±383.08)ng/mL in HBV-3p-siRNA group.The expressions of HBsAg were inhibited by HBV-3p-siRNA and HBV-siRNA compared with model group (F = 23.537 and 39.144, respectively;P =0.025 and 0.010,respectively).Serum level of HBV DNA was (2.54 ×104 ±1 .46 × 104 )copy/mL in model group,(2.22×104 ±2.62×103 )copy/mL in negative control group,(3.59×103 ±2.88×103 )copy/mL in HBV-siRNA group and (2.65 ×103 ±1 .46×103 )copy/mL in HBV-3p-siRNA group.Serum level of HBV DNA were inhibited by HBV-3p-siRNA and HBV-siRNA compared with model group (F =15 .013 and 16.741 ,respectively,both P <0.05 ).All of the indicated siRNA used in the experiments showed no apparent effects on the body mass index of the mice models.Conclusion HBV-3p-siRNA,which induces the production of IFN-β and inhibits HBV replication through gene silencing in vivo ,may be a powerful bifunctional antiviral molecule.
