Objective To investigate clinical significance of serum retinol -binding protein(RBP)in chron-ic hepatitis B(CHB)and liver cirrhosis after hepatitis B infection(LC).Methods 109 hospitalized patients were involved in this study.They were 51 patients with CHB,58 patients with LC.56 healthy individuals were selected as the the health controls(HC).RBP,ALT,AST,GGT,LDH,TBIL,PA and ALB were analyzed by automatic biochemical analyzer.Results Decreased serum RBP was observed in patients with CHB and LC(CHB vs.HC:t =8.06,P <0.01;LC vs.HC:t =10.26,P <0.01).In addition,the concentration of serum RBP in group of LC was lower than that in CHB(t =3.41,P <0.01).RBP was positively correlated with PA in patients with CHB and LC(CHB:r =0.856,P <0.01;LC:r =0.737,P <0.01),and RBP was positively correlated with ALB in patients with CHB and LC (CHB:r =0.571,P <0.01;LC:r =0.328,P <0.05).ROC analysis showed that area under the receiver operator characteristic curve(AUC)in CHB and LC were 0.874 and 0.942,respectively.Conclusion Serum RBP decreases significantly in patients with CHB and LC.Serum level of RBP is associated with severity of liver diseases and maybe a potential prognostic index for liver disease.

Objective To evaluate contrast-enhanced ultrasound(CEUS) in the diagnosis of vascular complications of transplanted kidneys.Methods Twelve patients with vascular abnormalities after renal transplantation were observed and analyzed using CEUS, and the diagnosis of all cases was confirmed by means of operation,pathology or angiography.Results Five patients with renal artery stenosis,2 patients with renal artery thrombosis,3 patients with pseudoaneurysm, 1 patient with pseudophlebangioma, and 1 patient with intrarenal extensive microthrombus were found.The coincidence of CEUS was 100%.Conclusions CEUS is a new method with the characteristics of non-nephrotoxic damage to kidney and comparable with angiography in terms of dynamic imaging.

Objective To elucidate the mechanism of accelerated apoptosis of monocytes in patients with lupus nephritis (LN). Methods 17 LN patients were enrolled in the study and 15 healthy volunteers were selected as controls. The expression of Faa and Fas ligand (FasL) was examined by immunofluorescent staining and flow cytometer analysis. The apoptosis and survival rate of monocytes cultured in vitro with human FasL (rHu-FasL) was analyzed by flow cytometer analysis and 5-diphenyl tetrazolium bromide (MTT) staining, respectively. Results Faa expression on monocytes was significantly higher in LN patients than that in healthy subjects. There was no difference of monocytes Fas expression between active LN patients and silent LN patients. There was no detectable FasL expression on monocytes from both LN patients and healthy controls. When monocytes cultured in vitro with rHu-FasL, there was a significantly increasing apoptosis and a decreasing survival rate of monocytes in LN patients as compared to healthy controls. Conclusion The up-regulated expression of functional Fas on monocytes may contribute to the accelerated apoptosis of monocytes in LN patients.

To elucidate the effects of pro inflammatory mediators on mRNA expression of AGE receptors in type B synovial cells, type B synovial cells from normal subjects were isolated and cultured in vitro with human serum albumin modified with advanced glycation end products (AGE HSA), tumor necrosis factor ?(TNF ?)and interleukin 1?(IL 1?). The expression of RAGE mRNA and AGE R3 mRNA was examined by RT PCR techniques. TNF ?, AGE HSA and IL 1? up regulated the expression of AGE R3 mRNA in type B synovial cells in a dose and time dependent manner. In contrast, TNF ? and AGE HSA down regulated the expression of RAGE mRNA in a dose and time dependent manner. IL 1? had no effect on RAGE mRNA expression. The regulatory responses induced by AGE HSA were blocked by a neutralizing polyclonal anti human TNF ? antibody, suggesting that the effects of AGE HSA were mediated by TNF ?. The proinflammatory mediators may regulate the gene expression of AGE receptors in type B synovial cells, and the regulatory role of these receptors is different in response to the proinflammatory mediators.

Objective To assess the value of intraoperative ultrasonography during the uterus septum resection under a hysteroscope.MethodsThe uterus septum resection was performed under the guidance of transabdominal ultrasonography by using a hysteroscope in 30 patients.The operative procedure and the position of the hysteroscope were monitored,and the depth of the dissection and thickness of the myometrium in the fundus uteri were measured with transabdominal ultrasound during the operation.ResultsThe thickness between the incisal surface and serosal layer in the fundus uteri was within the normal limits in 28 cases.In 2 cases,the tissue was over-ectomized.The position of the urethral catheter balloon was correct in all of the 30 cases.Three months after the procedure,reexamination by transvaginal ultrasonography showed that the uterine cavity was normal in the patients.ConclusionsIntraoperative ultrasonography is quick,safe and precise for monitoring uterus septum resection.It is valuable for establishing surgical strategy and reducing operative complications.

Objective To evaluate the value of ultrasound-guided channel establishment in minimally invasive percutaneous nephrolithotomy(MPCNL).MethodsBetween May 2006 and December 2007,85 patients received MPCNL in our hospital.Puncture points were selected and then channels were established under the guidance of ultrasonography according to the distributions of calculi during MPCNL.ResultsUnder the guidance of ultrasonography the puncture was completed at one session in all of our 85 cases.No massive hemorrhage or other severe complications occurred.In the cases,57 cases were cured after the first operation,and 27 cases received a second surgery.One of the cases was diagnosed as having calcification of the renal papillae without kidney calculi during the operation.Residual calculi(

Objective To investigate the expression of chemokine ligand 2 (CCL2)in chronic uric acid nephropathy(CUAN)and its diagnostic values in kidney damage.Methods 29 patients with CUAN[male 23,female 6,age (44.4 ±8.8)years old ]and 35 health individuals[male 27,female 8,age (40.6 ±7.8 )years old ]were involved in this study.Serum and peripheral blood mononuclear cells were isolated from peripheral blood.CCL2 was assayed by ELISA,and CD +45 /CD +14 monocytes were analyzed by flow cytometry.Liver &kidney functions,lipids and glucose were detected by automatic biochemistry analyzer.Results Serum CCL2 in group of CUAN and health con-trols were 456.2(202.6 -594.9)pg/mL and 245.0(132.2 -544.5)pg/mL,respectively(F =4.915,P =0.030). Percentages of monocytes in each group were 7.4%(5.6% -8.7%)and 6.1%(4.7% -7.9%),(F =8.891,P =0.004).Pearson analysis found that levels of CCL2 positively correlated with percentages of monocytes,serum uric acid and creatinine in CUAN group(r values were 0.535,0.584 and 0.012;P values were 0.003,0.001 and 0.012, respectively),but there was no correlation with urea and retinol binding protein(r value were 0.145 and 0.746,P val-ues were 0.453 and 0.453).Conclusion Hyperuricaemia may directly contribute to elevate levels of CCL2 and facilitate monocytes release into inflammation part to induce kidney damage.
