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.

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 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

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 measure the volume of hippoeampal formation(HPF) in healthy Chinese Han adults and provide database for researching on a variety of diseases associated with alteration of hippocampal structure. Methods This is a clinical multi-center study. One thousand Chinese healthy volunteers (age range = 18 to 70) recruited from 15 hospitals were divided into 5 groups, i. e. , Group A (age range = 18 to 30), B (age range =31 to40), C (age range =41 to 50), D (age range=51 to 60),and E (age range =61 to 70). Each group contained 100 males and 100 females. All of the volunteers were scanned by MR using T1 weighted three-dimensional magnetization prepared rapid acquisition gradient echo sequence. The margin of HPF were outlined manually for each side. Using multiple linear regression,relationships between hippocampal volume and sex, age, weight and height were analyzed respectively.Independent two sample t test was used to study the differences between male and female and between lcft and right. The differences of hippoeampal volume among age groups were analyzed by ANOVA. Results Hippocampal volume for left and right side were (4752 ± 659) and (5032 ± 660) mm3 respectively. The volume of HPF is significant correlated with gender and age, but without relevance to height and weight ( left and right r = 0. 283,0. 311, F = 30. 127,37. 050 ,P < 0. 01 ). The volumes of left and right hippocampus were (4897 ± 670), (5192 ± 667)mm3 respectively for men, and (4647 ± 624) and (4904 ± 630) mm3 for women. The right hippocampal volume was larger than the left ( t = 7. 030,6. 696, P < 0. 05 ). On both sides, men have larger hippocampus than that of women ( t = 6. 586,7. 326, P < 0. 01 ). The volumes of the left hippocampus among the five age groups in the male were (4981 ± 684), ( 5003 ± 609 ), (4976 ± 657 ),(4841 ± 631 ), (4631 ± 681 ) mm3 respectively, while the volumes of the right hippoeampus were (5340 ±647) ,(5276 ±582), (5264 ±620), (5133 ±661 ), (4894 ±699) mm3 respectively. Among age groups,the differences were statistically significant ( left and right F = 5. 737,7. 607, P < 0. 01 ). For male, there was significant difference of bilateral hippoeampus between the 18-30, 31-40, 41-50 years group and 61-70 years group ( P < 0. 05 ) and there was no significant difference among the other groups ( P > 0. 05 ).There was no significant difference of hippocampal among different groups in women (P > 0. 05 ).Conclusions With high-resolution MRI, the volume of the HPF was accurately measured, so as to provide the basic data for research of the hippocampus-related disease.
