OBJECTIVETo measure the plasma levels of transforming growth factor beta1 (TGFbeta1), the protein expression of alpha-SMA in hepatic stellate cells and urokinase plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1), and study on the relationships between the plasma levels of TGFbeta1, the protein expression and the serum hyaluronic acid (HA) in patients with different grades of hepatic fibrosis.
METHODSThirty seven cases with hepatic fibrosis of different grades were classified according to HE and VG staining categories from 0 to 4, in which there were 8 cases in grade 1, 9 cases in grade 2, 7 cases in grade 3, 13 cases in grade 4. The plasma levels of TGFbeta1 and the serum levels of HA were detected by ELISA. The protein expressions of a-SMA, uPA and PAI-1 in fibrotic liver tissue were observed by immunohistochemistry.
RESULTSWith the progression of hepatic fibrosis, the plasma levels of TGFbeta1 and the protein expression of a-SMA, uPA and PAI-1 in fibrotic liver tissue were increased. In grade 3 and 4, the plasma levels of TGFbeta and the protein expression of a-SMA and PAI-1 in fibrotic liver tissue were significantly increased, but the protein expression of uPA in cirrhosis liver tissue did not increased.
CONCLUSIONTGFbeta1, a-SMA, uPA and PAI-1 play an important role in the progression of hepatic fibrosis. Inhibiting the early activation of latent TGFbeta1 or increasing uPA and inhibiting PAI-1 over express may contribute to matrix degradation and retard the progression of hepatic fibrosis.

OBJECTIVETo investigate the effect of penehyclidine hydrochloride (PHC) in a rat model of renal injury induced by hemorrhagic shock and lipopolysaccharides (LPS).
METHODSForty-five healthy Wistar rats were randomized into sham operated group, model group, and 3 penehyclidine hydrochloride (PHC) dose (1, 2 and 3 mg/kg) groups (PHC1, PHC2, and PHC3 groups, respectively). The arterial blood samples were collected to determine the concentrations of serum tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), interleukin-1 (IL-1), urine creatinine (Cr) and blood urine nitrogen (BUN), and the renal tissues were collected to measure the expressions of ICAM-1 and nuclear factor-κB (NF-κB) and observe the pathological changes.
RESULTSTNF-α, IL-8, IL-1, Cr, BUN, ICAM-1 and NF-κB in the 3 PHC groups were significantly lower than those in the model group (P<0.05). TNF-α, IL-8, IL-1, Cr and BUN were significantly lower in PHC1 (P<0.05) than in the PHC2 and PHC3 groups, and ICAM-1 and NF-κB were similar between 3 PHC groups (P>0.05). Compared with the model group, the 3 PHC groups showed lessened pathological changes in the renal tubules.
CONCLUSIONPHC has protective effects against renal injury induced by hemorrhagic-endotoxin shock in rats, and treatment with 1 mg/kg PHC produces the most significant protective effect.

OBJECTIVETo investigate the clinical value of different magnetic resonance (MR) pulse sequences in diagnosis of spinal metastatic tumor.
METHODSFifteen patients with clinically suspected spinal metastatic tumor were included in this study. These patients were with documented primary tumors. Four MR pulse sequences, T1-weighted spin echo (T1WI SE), T2-weighted fast spin echo (T2WI FSE), short time inversion recovery (STIR), and gradient echo 2-D multi echo data imaging combination (GE Me-2D) were used to detect spinal metastasis.
RESULTSFifteen vertebral bodies were entire involvement, 38 vertebral bodies were section involvement, and totally 53 vertebral bodies were involved. There were 19 focal infections in pedicle of vertebral arch, 15 metastases in spinous process and transverse process. Fifty-three vertebral bodies were abnormal in T1 WI SE and GE Me-2D, 35 vertebral bodies were found abnormal in T2WI FSE, and 50 vertebral bodies were found abnormal in STIR. The verges of focal signal of involved vertebral bodies were comparatively clear in T1WI SE, comparatively clear or vague in T2WI FSE, vague in STIR, and clear in GE Me-2D.
CONCLUSIONSGE Me-2D may be the most sensitive technique to detect metastases. So three sequences (T1WI SE, T2WI FSE, GE Me-2D) can demonstrate the early changes of spinal metastasis roundly.
