To investigate the significance of liver biopsy in children with nephrotic syndrome,liver and renal biopsy samples were simultaneously examined with light microscopy,elctronic microscopy,and immunofluorescence in 10 patients. The results showed that all patients had abnormal liver histologic changes.Focal fatty degeneration in liver tissue was found under microscopic examination,and cytolysis and mild fatty degeneration were found in hepatocytes under electronic microscopic examination.The results suggested that disorder of lipid metabolism not only was toxic to glomeruli, but also deleterious to hepatocytes,then in turn enhanced abnormality in lipid metabolism. It is believed that hyperlipidemia is related to an increased anabolism of lipid and apolipoprotein, and reduction in catabolism of chylomicron and very low density lipoprotein .Therefore, with treatment of hyperlipidemia in these patients, it is possible to arrest progressive renal injury.

Objective To explore the value of placental alpha-microglobulin-1 in vagina liquid to diagnose premature rupture of membranes. Methods A prospective observational study to initial evaluation included both the standard clinical evaluation for rupture of membranes and placental alpha-microglobulin-1 immunoassay. Rupture of membranes was diagnosed if fluid was seen leaking from the cervical os or if two of the following three conditions were present: pooling of fluid, positive nitrazine test, or feming. Rupture of membranes was diagnosed definitively on review of the medical records after delivery. Results Placental alpha-microglobulin-1 immunoassay confirmed rupture of membranes at initial presentation with a sensitivity of 100% (89/89), specificity of 91% (10/11), positive predictive value of 99% (89/90), and negative predictive value of 100% (10/10),false positive rate of 9% (1/11). Placental alpha-nricroglobulin-1 immunoassay was better than the conventional clinical assessment in confirming the diagnosis of rupture ofmembranes (P<0.01). Conclusion Measurement of placental alpha-microglobulin-1 in cervicovaginal secretions is superior to conventional clinical assessment in the diagnosis of rupture of membranes.

Objective To determine the distribution and antibiotics resistance characteristic of pathogens in urinary tract infections in aged female diabetics patients and provide scientific basis for clinicians in selecting effective antibiotics. Methods Pathogenic bacteria, isolated from specimens of 107 elderly female diabetic cases with urinary tract infections, were identified and drug susceptibility tests were performed by VITEK-32 analysator. Results Among all 107 kinds of isolated bacteria,the ratio of gram-negative bacteria was 74. 8% ( 80/107 ), predominated by Escherichiacoli ( accounting for 48. 6% [52/107] ); the ratio of gramposition bacterias was 13. 1% (14/107) and eumycetes was 12. 1% (13/107). In antibiotic resistance analysis,the gram negative bacteria showed higher drug-resistance to the some common-antibiotics, such as ampicililin,cefazolin,cefuroxime-sodium and cefuroxime axetil ( > 70. 0% ), while they were sensitive to imipenem and amikacin( < 10. 0% ). The gram positive bacteria were most sensitive to vancomycin (0%), followed by Linezolid(7.7% ). Conclusion Escherichiacoli were the major pathogenic bacteria in urinary tract infections in aged female diabetic patients, with higher drug resistance. Therefore, drug resistance monitoring should be carried out according to the variety of pathogenic bacteria so as to guide rational use of antibiotics and decrease drug resistance.

Objective To investigate the protective effect of rhein lysinate (RHL)on the liver of the models with diabetic rats,and to provide basis for research on treatment of fatty liver in the patients with diabetes mellitus. Methods The models of diabetic rats were established by intraperitoneally injecting streptozotocin(STZ).40 rats were divided into control,model,25 mg·kg-1 RHL,and 50 mg·kg-1 RHL groups(n=10).The levels of malonaldehyde (MDA)and the activities of superoxide dismutase (SOD)and glutathione peroxidase (GSH-Px) were detected by thiobarbituric acid method, pyrogallol autoxidation method, and NADPH coupling method, respectively.The pathological changes of liver tissue were observed by hematoxylin and eosin (HE)staining;the content of fat in liver tissue was observed by Nile red staining;the expression levels of fat synthesis-related proteins were detected by Western blotting method.Results Compared with control group,the body weight of the rats in model group was decreased and the levels of blood glucose,total cholesterol(TC)and triglyceride(TG)were increased (P<0.05);the activities of SOD and GSH-Px in liver tissue were decreased (P<0.05);there were a plenty of fat vacuoles and fat accumulation in liver tissue. The signal pathway of fat synthesis-related ERK1/2-SREBP-1c was activated in model group;compared with model group,it was inhibited in 25 and 50 mg· kg-1 RHL groups (P<0.05).Compared with model group,the blood glucose,TC and TG of the rats in 25 and 50 mg ·kg-1 RHL groups were decreased (P<0.05);the activities of SOD and GSH-Px were increased (P<0.05);however the body weight had no change. Compared with model group, the fatty vacuoles and the fatty accumulation of liver tissue in 25 and 50 mg·kg-1 RHL groups were decreased. Conclusion The hepatic protection of RHL is correlated with the inhibition of oxidative stress, fat degeneration and fatty accumulation of liver tissues.

Objectives: The aim of the study was to evaluate the therapeutic effects of 6-mercaptopurine in the treatment of refractory childhood nephrotic syndrome (NS). Methods: According to the varieties of NS, 6-mercaptopurine (2 mg/kg body weight daily) combined with corticosteroid or 6-mercaptopurine (2 mg/kg body weight daily) alone after tapering of steroids were given to 28 consecutive children with primary NS in our hospital. Results: One month after the use of 6-mercaptopurine, proteinuria was decreased. The duration of improvement was 9~28 days, with mean duration of 17 days. Over-all effective rate was 85.7%. Among different varieties of NS, the best therapeutic effect was noted in steroid-dependent children; the better therapeutic effect in steroid-resistant children; and good therapeutic effect in frequently relapsing children. The effective rates were 100%, 84.6%, 81.8% respectively. All the pathological varieties of 28 children were confirmed by renal biopsy. The better therapeutic effects were noted in slight mesangial proliferative glomerulonephritis (MsPGN) and minimal change nephrotic syndrome (MCNS). The less therapeutic effect was noted in membranoproliferative glomerulonephritis (MPGN). Their therapeutic effective rates were 92.9%, 80%, 66.7% respectively. Unfortunately, drug-induced aplastic anemia was seen in 2 cases. Slight gastrointestinal reactions were present in 6 cases. There were no side reaction on the gonad. Conclusions: The great difference in the therapeutic effects is related to the different pathologic varieties of NS. With regard to the treatment of refractory NS in children, the pathological varieties should be confirmed by renal biopsy as soon as possible. Based on the renal biopsy, 6-mercaptopurine can be considered in the treatment of MsPGN and MCNS. As a result, relapses could be reduced; the duration of remission could be prolonged, and the side reactions from steroid treatment could be avoided. The use of 6-mercaptopurine for the treatment of refractory NS is one of the effective therapy.

ObjectiveTo investigate the clinical application of tacrulimus (TAC, FK506) in children with primary nephrotic syndrome (NS). MethodsSixty-five primary NS children received routine or decreased-dosage glucocorticosteroid according to clinical NS types after hospitalization. At the same time, TAC was given orally with the dosage of 0.1 to 0.15 mg/kg, once every 12 hours, for 6 to 24 months. And the serum concentration of TAC was monitored during the course. ResultsAfter the treatment of TAC for 1 to 2 months, 65 patients were recovered with gradually reduced urinary protein, rapidly increased serum albumin, and improvement of cholesterol and triglycerides. Total remission rate was 83.1% and onset time was 7 to 54 days. Twelve cases experienced recurrence. Increased CD4, as well as 3/3 or 3/1 TAC genotype, indicated higher remission rate. Various pathological types had different remission rates or ratio, which were as follows: minimal change nephropathy (96.4%), mesangial proliferative glomendonephritis (90.0%), membranous nephropathy (2/3), membranous proliferative glomerulonephritis (3/5), focal segmental glomerulosclerosis (4/9). The patients would recover in the course of treatment under the conditions of TAC initial dose as 0.1 to 0.15 mg /kg per 12 hours and controlled serum concentration as 5 to 10 g/L. During the treatment, 12 cases appeared gastrointestinal symptoms, mainly as anorexia, nausea and vomiting, 1 abdominal pain, 2 headache, 1 tremor, 1 paresthesia, 3 insomnia, 4 transient increased Scr, 8 slightly increased NAG, 6 increased C3 and α-2 macroglobulin. The symptoms disappeared within one week or after stopping TAC. ConclusionsTAC is effective in primary NS children, even with abnormal liver function or tuberculosis infection. TAC can also be a substitute to cyclosporine A.
