Objective To investigate the efficacy and safety of low-dose prednisone combined with methotrexate (MTX) and hydroxychloroquine (HCQ) in the treatment of rheumatoid arthritis (RA).Methods In this 12-week study,150 patients with active rheumatoid arthritis were randomly divided into two groups:prednisone group (70 cases who were received prednisone 5 ～ 10 mg/d + MTX 10 mg/w +HCQ 0.2 g/d) and control group (80 cases who were treated by Meloxicam 7.5 mg/d + MTX 10 mg/w +Leflunomide (LEF) 20 mg/d).The primary end-points were tender and swollen joint counts,visual analogue scales (VAS),and global physician and patients assessments of disease.The secondary end-points were morning stiffness time,C-reactive protein,erythrocyte sedimentation rate,the Health Assessment Questionnaire (HAQ),DAS28 and ACR20,ACR50.Results After 12 weeks,in terms of primary endpoints,tender and swollen joint counts,VAS and global physician assessments in the prednisone group were improved significantly [(4.5 ± 2.5),(3.2 ± 3.36),(21 ± 15),(24.2 ± 16.4),(20.2 ± 10.4) vs (6.4 ±5.84),(6.6±5.5),(46±14),(37.9±19.7),(34.1±12.4),P ＜0.05orP ＜0.01].In terms of secondary end-points,the prednisone group produced higher response rates [HAQ score (0.93 ± 0.52),CRP(10.2 ± 5.8) mg/L,ESR(30 ± 14) mm/h,morning stiffness time (32.0 ± 32.3) min,DAS 28 score (3.1±0.9) vs (1.22 ±0.81),(16.3±10.1)mg/L,(33±29)mm/h,(54.7±45.4)min,(4.9±1.9),P ＜0.05 orP ＜0.01].The incidence of adverse events was similar between two groups (43％ vs 49％,P ＞ 0.05).Conclusions Low-dose prednisone combined with MTX and HCQ produced rapid and relevant improvements in RA signs and symptoms.

Objective To investigate the morphologic abnormalities of myenteric plexus in diabetic rats and to explore the mechanism of its effect on gastrointestinal motility.Methods Thirty rats were randomly divided into diabetic group and control group.Gastrointestinal transit time was measured and histologic changes of cholinergic and nitriergic nerves in ileum myenteric plexus were observed with enzy- matic histochemistry.Results Four months after the establishment of the diabetic rats model,gastroin- testinal transit time was found delayed comparing with control group,the density of cholinergic neurons in the ileum myenteric plexus was decreased (P＜0.01) and the densities of nitriergic ganglions and neurons were significantly increased comparing with control group (P＜0.05 and P＜0.01).Conclu- sion Decrease of cholinergic nerves and increase of nitriergic nerves in the myenteric plexus of intestine is one of the mechanisms of delay gastrointestinal transit time in diabetic rats.

Objective To analyze the epidemiographic features of malignant tumors of urinary system in renal allograft recipients in our center.Methods A retrospective analysis was performed on 3150 patients who received renal transplantation between June 1978 and Autumn 2006.Twelve cases of urinary tumors were selected for study.Results Among 3150 recipients,33(1.05%)were diag- nosed as malignancies including 12(0.38%)cases in urinary system.The mean age of these patients when diagnosed as urinary tumors was 58.3?4.6(range 48-66).The mean duration of immunosup- pressive treatment was 62?18(range 26-120)months.Six cases received cyclosporine A+azalthio- prine+prednisone(CsA+Aza+Pred),5 cases cyclosporine A+mycophenolate mofetil+prednisone (CsA+MMF+Pred),and one case tacrolimus+mycophenolate mofetil+prednisone(FK506+MMF +Pred).Surgical treatment was carried out in 11 patients.Ten of them were still alive.One case died of cerebral hemorrhage.Conclusions Malignant tumors of urinary system,especially TCC is an im- portant complication in renal transplantation in our center.The occurrence of malignant tumors is inti- mately related to immunosuppressive treatment.The immunological status of patients after renal transplantation should be evaluated in follow-up studies.The treatment consists of complete resection of the mass,decreases of immunosuppressants,chemotherapy or radiotherapy.

Objective To observe the effects of creatine phosphate sodium on heart function and B -type natriuretic peptide in patients combination with ischemic cardiomyopathy and intractable heart failure .Methods 70 cases of coronary heart disease combined with ischemic cardiomyopathy and intractable heart failure were randomly ( with the random number table ) divided into the control group ( n=33) and the creatine phosphate sodium treatment group (n=37).The control group treated with conventional therapy (digitalis,diuretics,vasodilator,ACEI,et al) ten days;the treatment group with creatine phosphate sodium treatment on the basis of conventional therapy .The symp-tom,sign of the heart failure patients of the two groups before and after treatment were observed .NYHA cardiac func-tional grading were estimated.Echocardiography was used to detect left ventricular end -systolic diameter(LVESD), left ventricular end diastolic diameter ( LVEDD ) and left ventricular ejection fraction ( LVEF ); amino terminal pro brain natriuretic peptide (NT-proBNP) tested by laboratory of the two groups.Drug treatment for 10 days,the chan-ges of the indicators before and after treatment were observed .Results After treatment , compared with the control group[(50.63 ±4.67) mm,(61.30 ±4.58) mm].LVESD,LVEDD of the creatine phosphate sodium treatment [(47.16 ±4.30)mm,(57.92 ±4.30)mm]significantly decreased(t=5.73,4.96,all P<0.01),LVEF[(40.57 ± 4.51)%,(37.63 ±4.53)%]increased significantly(t =5.53,P<0.01).After ten days of treatment levels of NT-proBNP decreased in both two groups [(1 659.±248.18) pg/mL,1 899.3 ±205.45] than before treatment [2 043.46 ±217.04,(2 105.46 ±239.09)pg/mL](t=3.23,3.64,all P<0.05),and the decrease degree of the creatine phosphate sodium treatment group was more obvious than those of the control group (t=4.11,P<0.05). Conclusion Creatine phosphate sodium can improve the cardiac function and left ventricular ejection fraction of ischemic cardiomyopathy and intractable heart failurepatients ,enhance the clinical symptoms of patients .

Objective To explore the higher dangerous factors,the early clinical performances and its contents of neonatal pulmonary hemorrhage(NPH).Methods The clinical performances,chest radiograms and autoptical pathological materials of 66 cases of newborns who died of NPH at our neonatal department during 1993 to 2003 were reviewed and analyzed.Results The higher dangerous factors of NPH were premature delivery/low birth weight,serious diseases lead to hypoxia and severe infections.The early clinical performances of NPH were the suddenly aggravation of dyspnea and the increasing of moist sounds.The early X-ray performances were lower penetrance of lung fields extensively and well-distributly with path clouds,the intercostals space usually increased.According to the autoptical(patho)-logy,this X-ray perfomance indicated the edema of the pulmonary with small amount of hemorrhage.Conclusion The patients with the higher dangerous factors and the early clinical performances of NPH,must be diagnosed and interfered it as early as possible to reduce the mortality of NPH.

Objective To study the protective effect of redix astragail on intestinal mucosa barrier in infant rabbits with intestinal ischemiareperfusion.Methods Twenty male infant rabbits were divided into 4 groups randomly:sham control group,intestinal ischemia reperfusion(IIR) group(model group),redix astragail group,control group.Redix astragail group and control group intraperitonerlly injected redix astragail 6 mg/(kg?d)or sodium chloride preoperative.Intestinal mucosa and blood plasma superoxide dismutase(SOD) activity,intestinal mucosa tissue degree of injury were observed in infant rabbits with IIR.Meanwhile,the effect of redix astragail on them was studied.Results After IIR,SOD activity in intestinal mucosa and blood plasma obviously decreased,and intestinal mucosa tissue morphous and intestinal mucosa barrier lesion were progressively aggravated.Redix astragail might increase blood plasma and intestinal tissue SDD activity significantly.Conclusion Redix astragail plays an important role in protecting intestinal mucosa barrier in infant rabbits with IIR.

Objective To explore the pathological basis and clinical characteristics of children with congenital choledochal cyst(CCC) combined with liver damage.Methods According to the age,38 patients with CCC were divided into 2 groups:group A had 24 cases(ranged 6 months to 3 years old);group B had 14 cases(ranged 4 to 14 years old).A comparative analysis of them was conducted retrospectively in the clinical characteristics,hepatic pathological changes,perioperatively liver function and operation.Results Group A was obvious higher than group B in jaundice,white bole stool and abdominal mass,but group B was more in stomachache.Group A was obvious higher than group B in liver function lesion,alkaline phosphatase,bilirubin increase and blood coagulation disfunction(Pa
