Objective To investigate the efficiency and safety of articulating spacer for severe infected knee arthroplasty in patients with medical comorbidities and local sinus tracts. Methods Ten consecutive patients with medical comorbidities (rheumatoid arthritis, diabetes mellitus, etc) or local sinus tracts,who were complicated with late infected TKA, were included in the study. All the patients underwent twostage revision using articulating spacers. All of the patients were debridement thoroughly and followed by implantation of an antibiotic-loaded cement articulated spacer. Two-stage revisions were not followed untill the infection were controlled. The hospital for special surgery (HSS) knee scoring system and range of motion were used to evaluate the outcomes. Results One patient underwent knee fusion because the infection was not controlled after first-stage surgery. The other 9 patients had no evidence of infection. The mean follow-up was 50 months (range, 24-90 months), no recurrent infection developed for these 9 patients. The mean modified HSS score had improved from 48 points (range, 32-63) before the resection surgery to 79 points (range,62-91) at the end of the spacer period. At the latest follow-up, the modified HSS score averaged 89 points (range, 74-95). The good and excellent rate was 0, 80% and 100%, respectively. The average range of motion had increased from 13°-70° preoperatively to 8°-93° prior to the revision. And at the latest follow-up, the range of motion averaged 3° to 110°. Conclusion The delayed two-stage revision using an articulating spacer is effective in the treatment of chronically infected TKA characterized by simple, good reproducible, high rate of infection control, better joint function after surgeries

Objective: To investigate the effects of Fufang Jiangzhi No. 3, a compound traditional Chinese herbal medicine, on cholesterol-bile acid metabolism in rabbits with hypercholesterolemia and to explore the mechanism. Methods: Twenty-four male New Zealand white rabbits were randomly assigned into normal control group, untreated group and Fufang Jiangzhi No. 3 group, with 8 rabbits in each group. Rabbits in the untreated group and Fufang Jiangzhi No. 3 group were fed high cholesterol diet to induce hypercholesterolemia. After 4-week treatment, serum total cholesterol and bile acid contents were assessed. Activity of cholesterol 7alpha-hydroxylase (CYP7A1) in liver tissues was measured by enzyme-linked immunosorbent assay. The expressions of CYP7A1, bile salt export pump (BSEP) and small heterodimer partner (SHP) mRNAs in liver tissues were observed by real-time fluorescent quantitative polymerase chain reaction. Results: Compared with the normal control group, serum total cholesterol and bile acid contents in the untreated group were increased (P<0.01). Activity of CYP7A1 and expression of CYP7A1 mRNA were decreased and expressions of BSEP and SHP mRNAs were increased in liver tissues in the untreated group as compared with the normal control group (P<0.01). Serum total cholesterol level, and expressions of BSEP and SHP mRNAs in the Fufang Jiangzhi No. 3 group were lower than those in the untreated group (P<0.01). The CYP7A1 activity and expression of CYP7A1 mRNA in the Fufang Jiangzhi No. 3 group were increased as compared with the untreated group (P<0.01), however, there was no significant difference in bile acid between the Fufang Jiangzhi No. 3 group and the untreated group. Conclusion: Fufang Jiangzhi No. 3 can up-regulate the expression of CYP7A1 mRNA, raise the activity of CYP7A1, and inhibit the expressions of BSEP and SHP mRNAs to regulate the metabolism of total cholesterol in rabbits.

OBJECTIVETo investigate the relationship between chronic pyelonephritis (CPN) and immune function, and the therapeutic mechanism of Yishenkang granule (YSKG).
METHODSOne hundred and twenty patients of CPN were divided into 3 groups randomly, the YSKG group (treated with YSKG), the control A group (treated with Sanjin tablet) and the control B group (treated with western medicine). Serum levels of immunoglobulin (Ig), complement 3 (C3), interleukin-2 (IL-2), peripheral T-lymphocyte subsets, and urinary secretory immunoglobulin A (sIgA) were determined before and after treatment with monoclonal antibody assay, agar diffusion method, radioimmunoassay (RIA), and radioimmuno-equilibrium method, and compared with normal control.
RESULTSThere were disorders of T-lymphocyte subsets in CPN, lowering of serum Ig, C3 and urinary sIgA, and increase of blood IL-2 (P < 0.05 or P < 0.01). These abnormalities could be normalized after YSKG treatment.
CONCLUSIONFunctional disorders of cellular and humoral immunity exist in CPN patients of chronic stage, YSKG could correct the immune functional disorder, control the recurrence of CPN effectively and alleviate the immunopathological damage.

Objective To investigate the relationship between p53,COX-2,Bax,c-myc genes and colorectal carcinoma complicated with chronic schistosomiasis. Methods One hundred and sixty patients with colorectal carcinoma were selected and divided into two groups;a schistosomiasis group(colorectal carcinoma complicated with chronic schistosomiasis,n=80)and a non-schistosomiasis group(colorectal carcinoma uncomplicated with chronic schistosomiasis,n=80). The tissue microarray tech-niques and immunohistochemistry method were used in all the patients to detect the expressions of p53,COX-2,Bax and c-myc proteins. Results The positive rate and level of p53 protein expression in the schistosomiasis group were lower than those in the non-schistosomiasis group,but there were no significant differences between the two groups(both P>0.05). The COX-2 protein in both groups was positive,but the positive expression level of COX-2 in the schistosomiasis group was higher than that in the non-schistosomiasis group,and there was a significant difference between the two groups(P<0.01). The positive rate and level of Bax protein expression were not significantly different between the two groups(both P>0.05). The positive rate of c-myc expression in the schistosomiasis group was higher than that in the non-schistosomiasis group,with a significant difference(P<0.01),but the positive expression level was lower than that in the non-schistosomiasis group,and there was a significant difference between the two groups(P<0.01). Conclusions Schistosome infection may impact on the deficiency of p53 of human colorectal cancer cells. It may promote the excessive expression of COX-2 protein,which is an indirect carcinogenic factor. The expression of Bax gene has no correlation with schistosome infection. The schistosome chronic infection may cause a persistent low level expression of c-myc gene.
