Objective To study the therapeutic effects of Cordyceps polysaccharide (CP) on adenine-induced chronic renal failure(CRF)in rats. Methods CRF model was induced by Adenine ig .The rats were randomized into normal group, model group, CP high, moderate, Low-dosage groups and Dexamethasone group. The models of adenine-induced nephrosis were established by intragastric administration of adenine 300 mg/kg for 21 days. After treatment, renal function, biochemical indicators, kidney index, renal pathologic changes and serum TNF-? were observed. Results Compared with the model group, the degree injury of renal function in CP groups was palliated significant, renal pathologic changes were palliated significant, renal index and content of serum TNF-? were both decreased significant. Conclusion CP has a therapeutic and preventive effect on adenine-induced CRF, and can prevent the generation and development of CRF, improve renal function.

0.05).Conclusions Neither the new nor old SIRS diagnostic criteria had a high conforning rate with neonatal critical illnesses;There was no significant difference between them in each clinical item.It shows that the new SIRS diagnostic criteria is not superior to the old one,therefore we should improve the neonatal SIRS diagnostic criteria in the future.

ObjectiveControl study on the clinical efficiency and costs of fast track surgery(FTS) and traditional method was carried out in colorectal cancer patients. Methodsone hundred colorectal cancer patients were randomLy selected, 50 cases treated with conventional therapy as control group and 50 cases treated with FTS programme. The postoperative initial venting time, the incidence of complications, the hospital stay and cost index were compared between the two groups. ResultsThe postoperative initial venting time was in advance and postoperative stay was obviously shortened in FTS group. Hospitalization expenditure in FTS group was lower than that in control group. Patients recovered quickly, the result was satisfactory. The complication was not significantly different between the two groups (P ＞ 0.05 ) . ConclusionsFTS treatment can accelerate postoperative rehabilitation and elevate clinical efficiency in colorectal cancer patients during operation period. FTS treatment is a safe and effective method.

AimTo establish the model of adriamycin- induced nephritic syndrome in rats and its pathological change wasobserved. MethodsThe model of nephritic syndrome in rats was established by intravenous injection of adriamycin in the dose of 5mg · kg-1 and 3 mg · kg-1 respectively at the first day and 15 th day. The amount of urine protein was measured at the 1、2、3、4、6、8 and 12 th week and the serum biochemical pa rameters of TG, TCH, BUN, Cr, TP and ALB were detected at the 6 th and 12 th week. Results The urine protein and the serum biochemic parameters were increased significantly, except the TP and ALB, which were decreased. Pathological changes at the sixth week was similar to minimal changes in glomerulonephritis, and at the 12 th week, sclerosis of glomeruli of kidney could be found. ConclusionAfter first injection,the changes of kidney were like those inminimal change glomerulonephritis of human being. But after the second injection. The kidney had the changes of focal segmental glomeralosclerosis.

Objective To study the therapeutic effects of Cordyceps polysaccharide(CP)on chronic reanl failure(CRF) Rats.Methods CRF rat model was estblished by 5/6 nephrectomy.After the modeling,sixty adult SD rats were randomly divided into 6 groups:positive control group(receiving 0.1 mg/kg dexamethasone,im),high-,middle-and low-dose CP groups(gavage of CP at the dose of 160,80 and 40 mg/kg,respectively),sham-operation group(gavage of normal saline at the same volume of CP) and the model group(gavage of normal saline at the same volume of CP).After treatment for 14 days,biochemical indicator,renal function,and renal pathologic changes were observed.Results Compared with the model group,serum urea nitrogen,serum creatinine,urinary protein and urine volume were decreased in the positive control group and CP groups(P

Objective To investigate the protection effects of recombinant human tumor necrosis factor-α receptor Ⅱ :IgG Fc fusion protein for injection (rhTNFR:Fc) on rats with collagen-induced arthritis (CIA) and analyze osteopontin (OPN) changes following therapy in order to understand its primary mechanism of action. Methods CIA was induced by bovine Ⅱ collagen (B Ⅱ C) injection. Rats were treated with rhTNFR:Fc from the 13th day after the first injection of B Ⅱ C till the 36th day. The anterior-posterior diameters of ankle joints and weight were measured weekly. The pathological score was evaluated by HE staining and toluidine blue staining. The blood plasma TNF-α and OPN levels were measured by ELISA and the histology expression was evaluated by immuno-histochemistry. Comparisons between groups were performed with one-way ANOVA. Results Quantitative analysis showed pathological score in the model group and treatment group was significantly reduced in joint pathology (8.2±1.0 vs 4.8±1.4, P<0.05). The mean plasma levels of TNF-α and OPN values were (713±146) pg/ml, (4.3±0.6) ng/ml respectively in the model group,but those of the treatment group were (68±20) pg/ml, (4.2±0.6) ng/ml. Serum TNF-α values were significantly different (P<0.05) between the two groups, while no significant difference was found in the value of plasma OPN (P=0.688) between the two groups. rhTNFR:Fc could reduce the cells OPN expression in the interface layer of the synovium and cartilage (P<0.05). Conclusion Pathology scores and ELISA results haveshown that rhTNFR:Fc has good therapeutic efficacy. It can significantly reduce the bone and cartilage damage of CIA mouse model, and can significantly reduce the expression of OPN in the sliding joints, thereby delay disease progression. However, it can not reduce the expression of OPN in the peripheral blood plasma.OPN may be involved in bone destruction and resorption rather than in inflammatory process.

Objective To study the effect of flupentioxl melitracen and pinaverium bromide treatment on the changes of anorectal motility and rectal sensation in the patients of diarrhea-predominant irritable bowel syndrome (IBS-D) accompanying with depression and/or anxiety status. Methods Forty-four patients with IBS-D accompanying with depression and/or anxiety status were divided into group A (flupentioxl melitracen and pinaverium bromide) and group B (pinaverium bromide) by random digits table,and treated for 4 weeks. Twenty-five healthy subjects were included as control group. The anorectal motility and rectal sensation before and after taking medicines were compared. Results When abdominal pressure was increased, the net increased pressure of anal sphincter was (3.0 ± 1.2 ) kPa in group A and (2.9 ± 1.2)kPa in group B. They were lower than that in control group [(3.6 ± 1.6) kPa](P＜ 0.05). The rectal lowest volume of sensory threshold, the maximal volume of tolerance and maximal compliance were (55 ± 20) ml,( 145 ± 78 ) ml, ( 21.9 ± 12.9 ) ml/kPa in group A, ( 56 ± 38 ) ml, ( 150 ± 50 ) ml, (20.8 ± 11.2) ml/kPa in group B. They were lower than those in control group [(80 ± 38 ) ml, ( 190 ± 50 ) ml, (30.8 ± 15.2 ) ml/kPa](P ＜ 0.01 ). The rectal lowest volume of sensory threshold, the maximal volume of tolerance and maximal compliance were higher than those before taking medicines. Only the rectal lowest volume of sensory threshold in group B was higher than that before taking medicines. The rectal lowest volume of sensory threshold, the maximal volume of tolerance and maximal compliance in group A after taking medicines were higher than those in group B (P ＜ 0.05 or ＜ 0.01 ). Conclusions Higher sensitivity, lower tolerance,lower compliance of rectum and weakened anal automatic control function in IBS-D may be associated with diarrhea and frequent defecation. Treatment combining flupentioxl melitracen with pinaverium bromide may preferably improve the aperception functions of rectum in the patients of IBS-D accompanying with depression and/or anxiety status.
