ABSTRACT
OBJECTIVE: We intended to evaluate the diagnostic efficiency of red cell distribution width to platelet ratio(RPR),and compare it with other three markers of fibrosis-4(FIB-4), aspartate aminotransferase-to-platelet-ratio-index(APRI) and aspartateaminotransferase-to-alanine aminotransferase ratio(AAR) for judging liver fibrosis and fibrosis severity in patients with chronic hepatitis B(CHB). METHODS: who had not received antiviral treatment met the requirements of this cross-sectional study. Hematology,biochemistry, virology testing and liver biopsy were performed. Receiver-operating characteristic curves were constructed and the area under the ROC curve was calculated. RESULTS: The cut-off value for distinguishing F0-1, F2-3 and F4 was 0.079, 0.141 and 0.279,respectively(P<0.001) for RPR; 1.194, 3.703 and 4.383(P<0.001) for FIB-4; 0.384, 0.660 and 1.441, respectively(P<0.001) for APRI; and 0.915, 0.850 and 0.960(P=0.706) for AAR. The sensitivity was 76.09% for RPR, 78.26% for FIB-4, 97.83% for AAR and80.43% for APRI; specificity was 81.48% for RPR, 75.93% for FIB-4, 14.81% for AAR and 80.43% for APRI; the AUROC was 0.787 for RPR, 0.778 for FIB-4, 0.540 for AAR and 0.759 for APRI. The common cut-off value was 0.11, 1.94, 0.60 and 0.59 for RPR, FIB-4, AAR and APRI respectively. CONCLUSION: RPR, FIB-4 and APRI have good efficiency in appraising significant and severe fibrosis in patients with CHB, however RPR is superior to FIB-4 and FIB-4 is superior to APRI, therefore, RPR is a better index in evaluating liver cirrhosis.
ABSTRACT
<p><b>OBJECTIVE</b>To study the influence of compound Biejia Ruangan Prescription (CBRP) on extracelluar matrix in bleomycin induced pulmonary fibrosis rats.</p><p><b>METHOD</b>54 male Sprague-Dawley rats were randomly divided into 6 groups (9 rats in each group). Rats in the model control group, positive medicine group, and high, moderate and low CBRP groups were injected with bleomycin A5 by trachea, and rats in sham-model control group with same volume normal saline. 29 days after the injection, CBRP solution of different dosages (1.4 g x kg(-1), 0.7 g x kg(-1), 0.35 g x kg(-1)) was respectively given to rats in the high, moderate and low CBRP group by gavage, while equal volume of normal saline was given to those in the sham-model control group and model control group, and an equal volume of prednisone (0.56 mg x kg(-1)) was given to those in positive medicine control group. On the 80th day, the levels of III-collagen, IV-collagen, laminin and hyaluronic acid in the serum were determined, the determination of hydroxyproline in lung homogenates was analyzed, and the right lung was incised to make pathological sections which were stained with Hematoxylin-Eosin (HE) and Masson staining for pathological diagnosis.</p><p><b>RESULT</b>CBRP could decrease the levels of III-collagen, IV-collagen, laminin and hyaluronic acid in the serum.</p><p><b>CONCLUSION</b>CBRP may play its therapeutic role by leveling down the content of extracellular matrix in rats with pulmonary fibrosis induced by Bleomycin A5.</p>

<p><b>OBJECTIVE</b>To study effects of soy extract on lipid metabolims in ovariectomized rats.</p><p><b>METHOD</b>90 Wistar rats were randomly divided into 9 groups: control group, sham group, model group, estrogen group, soy isoflavone group of high dose, soy isoflavone group of low dose, soy extract of high dose, soy extract of low dose, and soy polysaccharde group, 10 rats in each group. Except fer of control and sham groups, the test rats were ovariectomized. One week after operation, the rats were treated with different drugs. Six weeks after operation, the rats were killed, with serum and liver taken, and serumglycerol(sGT), cholesterol(sGC), LDL, HDL and liver homogenate hGT, hGC, measured.</p><p><b>RESULT</b>The level of sGC, LDL in ovariectmized rats increased significantly, compared with that in control and sham groups. In liver both the level of hGT and hGC were higher than that in liver from control and sham groups. Administration of estrogen or soy extract or soy isoflavone could attenuate these in ovariectomized rats, but soy polysacchardes did not have any effects.</p><p><b>CONCLUSION</b>Ovariectomized rats have an imbalance of lipid metabolism, the level of hGT and hGC were increased, and administration of estrogen, soy extracts or soy isoflavone could decrease these changes induced by ovariectomizing.</p>
