Objective The current study was to investigate the clinical and pathological features of macroscopic hematuria associated acute kideny injury (MH-AKI) in patients with IgA nephropathy (IgAN) and its associated prognostic factors.Methods We performed an analysis on the clinical and pathological features of biopsy-proven IgAN patients diagnosed during 2004 to August of 2007,who had experienced MH associated AKI.The patients enrolled in the study were followed up.The renal lesions were evaluated with Katafuchi pathological scores of IgAN.Results 5 patients with IgAN had experienced at least one episode of MH-AKI,accounting for 1.3% of IgAN diagnosed during the same period and 13.5% of IgAN patients with macroscopic hematuria.High proportion of tubules filled with red blood cell casts and tubular injury were demonstrated in all biopsy specimens.Renal function of 3 patients completely recovered within 14 days.One patient (patient 4) got quick recovery in the first month of the disease but completely recovered 418 days later.The other patients only had an incomplete recovery during the 20-month follow-up.The incompletely recovered one had relatively an older age,longer persistence of MH,more sclerotic glomeruli and a more severe tubule-interstitial damage.Conclusion AKI is commonly seen during episodes of MH in patients with IgAN.Not all patients with MH-AKI showed a complete recovery.Age,duration of MH,proportion of glomerular sclerosis and the severity of tubular necrosis might be the risk factors of an incomplete recovery of renal function.

Epilepsy is a common nervous system seizure disease in children,20%-30% of them is intractable epilepsy.The pathogenesis of intractable epilepsy in children is not yet identify.Some research think that this may be associated with resistance of a variety of diffe-rent mechanisms of antiepileptic drug and abnormalities of multidrug resistance gene expression.The most investigation of multidrug transpor-ter is P-glycoprotein,multidrug resistance-associated protein.They are present in cell membrane and belong to adenosine triphosphate-dependent membrane transport protein.Studies have showed that over-expression of multidrug transporter in temporal lobe brain tissue of patients with refractory epilepsy and animal model of chronic epilepsy reduce the concentration of therapeutic drug in cells.They result in resis-tance by releasing the energy and transferring large amounts of anti-epileptic drugs to exterior of brain capillary endothelial cells in way of active transport.The relationship between multidrug transporter′s structure,distribution,functions and drug-resistant epilepsy are reviewed.

SUMMARY We analyzed the clinicopathological characteristics of one patient with Rhupus syndrome as-sociated nephropathy in Peking University People ’s Hospital, and reviewed the related literature .The pa-tient was a middle aged female .She developed rheumatoid arthritis first , and then manifested mild sys-temic lupus erythematosus together with positive anti-neutrophil cytoplasmic antibodies ( ANCA ) and cryoglobulinemia several years later .The renal biopsy was performed and manifested as lupus nephritis . The transmission electron microscopy revealed cryoglobulinemia associated renal damage .This report shows that the clinicopathological characteristics in patients with Rhupus syndrome associated nephropathy are complicated .The renal pathology can be used as a diagnostic tool .

Objective To evaluate the respiratory mechanics and inflammatory status in elderly patients with stable chronic obstructive pulmonary diseases (COPD).Methods The arterial blood gases (ABGs),respiratory drive and its derivatives,mechanics of respiratory muscles,resistance and compliance of airway,interleukin-8 (IL-8)and interferon-?(IFN-?)were measured in 42 cases withstable COPD and 40 subjects of normal control.Results The elderly patients with stable COPD had great changes in the following parameters while compared with the control group:peak inspiratory pressure(PIMAX) [(4.48?2.11)vs(6.10?2.91)kPa],maximum expiratory pressure (PEMAX)[(6.30?3.20)vs(9.15?93.30)kPa],0.1s mouth occlusion pressure(P_(0.1)) with its correction index,airway resistance,compliance,ABGs,the levels of IL-8[(218.46?91.14) vs (161.84?14.40)ng/L]and IFN-?[(2435.82?639.92)vs(1652.40?95.08)ng/L],which might aggravate the progress of COPD consistently.Conclusions The elderly patiends with stable COPD has marked changes in respiratory drive,airway resistance,and airway compliance,respiratory mechanic and inflammatory status.The intervention should be performed in the elderly stable COPD patients.

OBJECTIVETo explore clinical efficacy of Yiguanjian Decoction (YD) combined Adefovir Dipivoxil Tablet (ADT) in treating HBeAg negative chronic viral hepatitis B (CVHB) active compensated liver cirrhosis (LC) patients.

METHODSTotally 68 HBeAg negative CVHB active compensated LC patients initially treated were assigned to the treatment group and the control group using random digit table, 34 in each group. Patients in the control group took ADT alone, 10 mg each time, once per day. Those in the treatment group additionally took YD, one dose per day. The therapeutic course for all was 48 weeks. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil) were detected once in every two weeks. Hepatitis B virus (HBV)-DNA and four items of serum liver fibrosis [procollagen type I (PCN), hyaluronidase (HA), procollagen III peptide (PCIII), laminin (LN)] were detected once per every 4 weeks. Abdominal ultrasound B was performed before and after treatment. The inner diameter of the portal vein and the size of spleen were recorded. The fibrosis degree of liver was evaluated using Fibroscan. Efficacy of Chinese medicine (CM) was evaluated between the two groups before and after treatment using CM syndrome integrals. Efficacy of Western medicine (WM) was also evaluated between the two groups using Child-Pugh grading. Results Compared with before treatment in the same group, ALT and AST levels restored to normal levels, HBV-DNA turned negative (HBV-DNA < or = 1 x 10(2)) in the two groups after 48-week treatment. Besides, levels of TBil, ALB, PCIV, HA, PCIII, and LN obviously decreased (P < 0.05, P < 0.01). Results of ultrasound B showed the inner diameter of the portal vein and the size of spleen decreased. Fibroscan results showed that the elasticity value of the liver obviously decreased (P < 0.05). Besides, post-treatment levels of PCIV, HA, PCEJ, and LN, and the elasticity value of the liver decreased more obviously in the treatment group than in the control group (P < 0.01). There was no statistical difference in post-treatment levels of ALT, AST, TBil, ALB, inner diameter of the portal vein, or the size of spleen between the two groups (P > 0.05). Compared with before treatment in the same group, scores of Chinese medical syndrome and Child-Pugh scores decreased in the two groups after treatment (P < 0.05, P < 0.01). Besides, scores of Chinese medical syndrome decreased more obviously in the treatment group than in the control group (P < 0.05). The effective rate was 8824% (30/34) in the treatment group, higher than that of the control group [67.65% (23/34)] with statistical difference (P <0.05). Conclusion Combined treatment of YD and ADT could significantly improve symptoms of CM and fibrosis degree of liver of HBeAg negative CVHB active compensated LC patients.
