OBJECTIVETo observe effects of ginsenoside-Rb (G-Rb) on total cholesterol, lipoprotein cholesterol metabolism and anti-oxidation in experimental hyperlipidemia rats.

METHODHyperlipidemia rats were respectively given G-Rb 50, 100, 200 mg x kg(-1) x d(-1) ig for twelve days. Total cholesterol, lipoprotein cholesterol and lipid peroxidation (LPO) contents, prostacycline (PGI2), thromboxane (TXA2), superoxide dismutase (SOD) and blood viscosity were measured. Fat accumulation in liver was also observed.

RESULTTriglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-c) in serum, TXA2 in plasma, LPO in serum and liver, and blood viscosity were decreased significantly. High density lipoprotein cholesterol (HDLc) in serum, PGI2 in plasma and SOD in serum and liver were significantly increased by G-Rb (100, 200 mg x kg(-1)) in experimental hyperlipidemia rats. In addition, G-Rb could decrease TC/HDL-c, LDLc/HDL-c ratio, increase PGI2/TXA2 ratio and inhibit fat accumulation in liver.

CONCLUSIONG-Rb could have anti-arteriosclerosis effect by improving cholesterol and lipoprotein-cholesterol metabolism, suppressing lipid peroxidation, increasing anti-oxidase activity and PGI2/TXA2 ratio.

Papillary adenoma (PA) of kidney is defined as a lesion measuring less than 15 mm and featuring papillary or tubular architecture along with nuclei of low grade.Clear cell renal cell carcinoma (CCRCC) is the most common seen group of malignant neoplasms consists of cells with clear or eosinophilic cytoplasm.The coexistence of these two kinds of tumor is rare and was only reported in one piece of literature to date.We report a thought-provoking case in which CCRCC is coexisting with multiple PAs.The CCRCC shows no difference with other common cases while the PAs share the same clinical and pathological features with other ones and demonstrates no amplifying of 3,7 or 17 chromosome.However,the multiple PAs were neglected by imaging doctors and surgeons,and some tiny lesions were not found until the observation under microscope.This case reminds that patients accepting partial nephrectomy for CCRCC may have PAs,so attention should be paid to the image studies along with routine pathological examination of kidney for that there may exists two or more kinds of lesions.

Objective To construct a modified and enhanced thymidine kinase (TK) vector regulated by human telemerase catalytic subunit promoter (hTERT) promoter and cytomegaiovirus (CMV) enhancer and its killing effect on nasopharyngeal carcinoma in vitro and in vivo and its safety in vivo. Methods The pGL3-basic,as basic vector template,was linked and constructed into TK vector regulated by hTKRT promoter and CMV enhancer with mono-promoter vector as control. Enhanced TK expression was confirmed by fluorescent microscopy and real time fluorescent quantitative PCR. Telomerase activity was measured by stretch PCR. Tumour killing effects were examined by MTT and Boyden areole. The effects of enhanced TK on the invasiveness of tumor cell NPC 5-8F and the growth of xenograft implanted in nude mice were investigated. Results Compared with non-enhanced vector, TK expressed by the enhanced vector significantly increased in NPC 5-8F and MCF-7 cells,telomerase activity was positive in human in NPC 5-8F cells and breast cancer MCF-7 cells and negative in control human blood vessel endothelium ECV-304 cells. After ganciclovir (GCV) treatment, NPC 5-8F cell survival rate and invasiveness decreased and tumor progress of NPC xenograft implanted in nude mice was inhibited, without obvious toxicity effects on mouse liver and kidney. Conclusions The enhanced TK vector regulated by hTERT promoter and CMV enhancer can obviously and specifically inhibit and kill nasopharyngeal carcinoma cells in culture and nasopharyngeal carcinoma xenograft in nude mice in vivo, without obviously toxic side effects on nude mice. The targeted and enhanced TK gene vector with high performance may be a new tumour targeted gene therapy strategy clinically to aim directly at most malignant tumours including nasopharyngeal carcinoma, with more extensive anti-cancer spectrum.

This study was purposed to explore the expression of glucosylceramide synthase (GCS) in human leukemia cells and its relationship with multidrug resistance. RT-PCR was used to analyze peripheral blood samples from 53 leukemia patients with multidrug resistance/non-resistance, and to detect the expression level of GCS gene in HL-60 cells and HL-60/ADR cells, the expression level was compared with the level of mdr-1. The expressions of GCS protein and P-gp protein in HL-60 cells and HL-60/ADR cells were assayed by Western blot analysis. The results showed that the relative optical density ratio of GCS gene amplified bands in samples of leukemia patients with drug-resistance was significantly higher than that in samples of leukemia patients with drug non-resistance group (P < 0.05), meanwhile the significant enhancement of optical density value of GCS gene amplified bands accompanied by high expression of mdr-1 gene. Their correlation showed positive (P < 0.01, r = 0.6). The GCS mRNA and protein were overexpressed in HL-60/ADR cells, and their expression levels were obviously higher than that in HL-60 cells, meanwhile the expression of mdr-1 mRNA and P-gp also significantly increased in HL-60/ADR cells. It is concluded that the high level of GCS in leukemia patients possibly is associated with multidrug resistance of leukemia cells.

OBJECTIVETo understand antibody responses to and RNA sequences of Hantavirus in patients with hemorrhagic fever renal syndrome (HFRS) in Yantai areas and to demonstrate the type of the prevalent viruses caused HFRS.

METHODSSerum specimens collected at acute and convalescent stages from 90 patients with HFRS and IgM and IgG antibodies against Hantavirus were detected with ELISA, and cross plaque reduction neutralizing tests were performed to detect neutralizing antibody. Viral RNA was extracted from the patients? sera by using Trizol method and nested PCR was utilized to amplify the specific segments of the viral cDNA and the products of the PCR were TA cloned and then the nucleotide sequences were determined.

RESULTSThe IgM antibody was positive in 82.2% (88/107) of the patients while the IgG antibody was positive in 85.7% (66/77) of the patients. Both the serologic and sequence analyses demonstrated that the epidemic of HFRS in Yantai areas was caused by mixed types of Hantavirus. The prevalent strains of Hantavirus had higher homology with the strains isolated in Korea than with those isolated previously in China.

CONCLUSIONSThe serologic and sequencing analyses indicated that the epidemic of HFRS in Yantai areas was caused by mixed types of Hantavirus dominated by type SEO.

OBJECTIVETo study the clinicopathologic features of microscopic polyangitis (MPA), and to compare the differences in anti-neutrophil cytoplasmic autoantibody (ANCA)-positive and ANCA-negative patients, as well as in ANCA-positive cases with or without glomerular immunoglobulin deposition.

METHODSThirty-four biopsy-proven cases of MPA were retrieved from the archival files of the Department during the past 7 years. The clinicopathologic characteristics between ANCA-positive and negative patients, as well as between ANCA-positive cases with and without glomerular immunoglobulin deposition, were compared.

RESULTSAmongst the 34 MPA patients studied, about one-fifth to one-half were accompanied by various extrarenal symptoms. Serum ANCA was positive in 26 patients (76.5%). A slight to moderate increase in urinary protein was demonstrated in 31 patients, while 3 patients had nephrotic syndrome. Elevated serum creatinine was detected in 32 cases. Renal biopsy revealed crescentic glomerulonephritis in 24 cases, focal segmental glomerulonephritis in 8 cases, vascular fibrinoid necrosis with inflammation in 7 cases, intimal thickening of arterioles in 24 cases, interstitial inflammatory cells, including neutrophil infiltration (21 cases), in 29 cases. Crescentic formation was more common in the ANCA-positive group than in the ANCA-negative group (P < 0.05). Amongst the 26 ANCA-positive cases, 10 had glomerular immunoglobulin deposits (including 1 case with IgA nephropathy). In general, these cases had a greater degree of proteinuria than those without glomerular immunoglobulin deposits (P < 0.05).

CONCLUSIONSThe diagnosis of MPA relies on histologic examination of renal biopsy and clinicopathologic correlation. Serum ANCA seems important for glomerular crescent formation. Glomerular immunoglobulin deposition may also play a significant role in the exacerbation of proteinuria.

OBJECTIVETo study the expression of neonatal Fc receptor in podocytes in human nephritis and immune-induced rat nephritis models: anti-Thy1.1 nephritis and Heymann nephritis.

METHODSThirty-nine cases of renal biopsies were enrolled from September 2009 to February 2010, including 8 cases of minimal change disease, 4 cases of focal segmental glomerulosclerosis, 9 cases of membranous nephropathy, 12 cases of IgA nephropathy and 6 cases of lupus nephritis. Five normal kidney tissue samples adjacent to renal clear-cell carcinoma were served as normal controls. Laser capture microdissection and real-time RT-PCR were used to assess the expression level of FcRn mRNA in glomeruli of various glomerulonephritides, and immunohistochemistry (IHC) of FcRn by SuperVision method was performed. In addition, rat models of mesangial proliferative nephritis (anti-Thy1.1 nephritis) and passive membranous nephropathy (Heymann nephritis) were established and FcRn was examined in renal tissues by IHC.

RESULTSThe FcRn mRNA level in lupus nephritis was statistically higher than that of normal controls (P < 0.05). FcRn protein expression by IHC was seen in lupus nephritis (6/6), membranous nephropathy (6/9) and IgA nephropathy (7/12), significantly higher than that of normal controls (0/5), P < 0.05. Minimal change disease and focal segmental glomerular sclerosis showed minimal or none expression of FcRn (1/8, 0/4 respectively) and not statistically difference from that of normal controls. Furthermore, FcRn expression in podocytes was detected in rat anti-Thy1.1 (3/5) and Heymann nephritis models (2/7) but was not detected in normal controls.

CONCLUSIONSExpression of FcRn in podocytes was up-regulated in immune-induced human nephritis and rat nephritis models of anti-Thy1.1 nephritis and Heymann nephritis. FcRn may play a role in the development of immune-induced glomerulonephritis.
