OBJECTIVETo explore the effects of harmful factors in tank cabins on renal function of tank crews.
METHODSOne hundred and fifty two tank crews as the observation group and 37 soldiers without tank environment exposure as control group were selected in the study. α1-microglobulin(α1-MG), β2-microglobulin(β2-MG), IgG, N-acetyl-β-glucosidase (NAG) and urinary albumin excretion rate (UAER) in morning and 24 h urine were measured.
RESULTSCompared to the control group, the levels of α1-MG, β2-MG, NAG, UAER in observation group were increased significantly (P < 0.05). β2-MG, NAG, UAER of Soldiers with more than 50 motorized hours in observation group were significantly higher than those of control group (P < 0.05). β2-MG, NAG and UAER of soldiers divorced from tank occupation more than 3 years decreased to the normal levels. β2-MG of soldiers divorced from tank occupation more than 10 years was significantly higher than that of 6-10 years group.
CONCLUSIONTank occupational exposure influences the renal function of tank crews but not to a degree of clinical kidney disease. The renal function of crews divorced from tank occupation may recover but dysfunction of renal tubular reabsorption still exists.

OBJECTIVETo observe and compare the effects of Hanfangji Compound and IFN-gamma on expressions of transthyretin (TTR) , inter-alpha inhibitor H1 (ITIH1) and serpin peptidase inhibitor clade F member 2 (SERPINF2) of hepatic stellate cells (HSC-T6).
METHODHanfangji Compound and IFN-gammaof different concentrations were used in hepatic stellate cell-T6 (HSC-T6) for 48 h. Flow cytometer was used to detect the effects of Hanfangji Compound and IFN-gamma on HSC proliferation. RT-PCR method was adopted to detect mRNA expressions of TFR, ITIH1 and SERPINF2. TTR, ITIH1 and SERPINF2 secretions were detected by ELISA. The protein localizations of TTR, ITIH1 and SERPINF2 were examined by immune fluorescence. The protein expression of TfR and ITIHI were determined by Western blot.
RESULTAfter Hanfangji Compound and IFN-gamma were adopted in HSC-T6, compared with the control group, the cell proliferation was inhibited obviously (P < 0. 05) , protein expressions of TTR, ITIH1 and SERPINF2 and mRNA expression increased significantly, with certain correlation with concentrations of Hanfangji Compound. The 2. 5 g L-I Hanfangji Compound group was superior to the IFN-gamma group (P <0. 05).
CONCLUSIONHanfangji Compound can inhibit HSC proliferation, upregulated TTR, ITIH1 and SERPINF2 proteins and mRNA expression, which may be one of mechanisms of anti-hepatic fibrosis of Hanfangji Compound.

Preeclapsia (PE) is a severe disorder that occurs during pregnancy, leading to maternal and fetal morbidity and mortality. PE affects about 3-8% of all pregnancies. In this study, we conducted liquid chromatographymass spectrometry/mass spectrometry (LC-MS/MS) to analyze serum samples depleted of the six most abundant proteins from normal and PE-affected pregnancies to profile serum proteins. A total of 237 proteins were confidently identified with < 1% false discovery rate from the two groups of duplicate analysis. The expression levels of those identified proteins were compared semiquantitatively by spectral counting. To further validate the candidate proteins with a quantitative mass spectrometric method, selective reaction monitoring (SRM) and enzyme linked immune assay (ELISA) of serum samples collected from pregnant women with severe PE (n = 8) or normal pregnant women (n = 5) was conducted. alpha2-HS-glycoprotein (AHSG), retinol binding protein 4 (RBP4) and alpha-1-microglobulin/bikunin (AMBP) and Insulin like growth factor binding protein, acid labile subunit (IGFBP-ALS) were confirmed to be differentially expressed in PE using SRM (P < 0.05). Among these proteins, AHSG was verified by ELISA and showed a statistically significant increase in PE samples when compared to controls.
