Objective To analyze the variation tendency of correlative test indexes in the patients with type 2 diabetic mellitus (T2DM) and diabetic nephropathy (DN) .Methods The urinary microalbumin (M‐Alb) ,blood glucose and renal function were de‐termined in 167 cases of T2DM .Then the cases were divided into the simple DM group ,early DN group and clinical DN group ac‐cording to the excretion rates of urinary M‐Alb .The determined results were compared among 3 group and analyzed .Results The age in the simple DM group was smaller than that in the early DN group and clinical DN group (P<0 .05) .The positive rates of u‐rinary M‐Alb and urinary protein were highest in the clinical DN group ,the differences among 3 groups had statistical significance (P<0 .05) .The difference of blood glucose indexes had no statistical difference between the simple DM group and early DN group , the clinical DN group was apparently higher than that in the simple DM group and early DN group (P<0 .05) .The levels of urea (Urea) and creatinine(Cr) in the simple DM group were significantly lower than those in the early DN group and clinical DN group ,the differences among 3 groups had statistical significance (P<0 .01) .Conclusion The severe the DN ,the higher the urina‐ry M‐Alb ,blood glucose and renal function indicators ,the higher the positive rates of urinary protein and urinary glucose ,the more significant the tendency of renal function damage .

Aim To investigate the effect of Rhein on the movement and invasiveness of human ovarian carci-noma cells with directional high lymphatic metastasis SKOV3-PM4 cells and explore the role of Rac1/LIMK1/cofilin signaling pathway. Methods Migration assay and invasion assay were used to observe the effect of Rhein on the metastatic and invasive ability of SK-OV3-PM4 cells in vitro. The effect of Rhein on the morphology and cytoskeleton ultrastructure of ovarian cancer cells was observed by laser scanning confocal microscope and scanning electron microscope. The protein expression level of Rac1,LIMK1,PAK1 and co-filin were detected by Western blot, respectively. Re-sults Rhein inhibited the abilities of cell invasion and migration of SKOV3-PM4 cells,and the inhibitory rate increased along with the increase of the concentration and treatment duration. After treated with 8. 80 μmol· L-1 ,17. 60 μmol · L-1 , 26. 40 μmol · L-1 of Rhein for 24 h,the abilities of migration and invasion of SK-OV3-PM4 cells were inhibited ( P <0. 05 ); the mor-phology and cytoskeleton ultrastructure of SKOV3-PM4 cells were changed, cellular pseudopod reduced, cell microfilament fractured and its distribution disordered, plasma membrane was uneven and cell gap widened . After treatment of Rhein and Rac1 inhibitor , Rac1 protein expression and the expression of P-LIMK1 , P-PAK1 and P-cofilin notably decreased in a dose-de-pendent manner compared with the control group ( P<0. 05 ) . After Rhein and Rhein plus Rac1 inhibitor treatment ,P-LIMK1, P-cofilin, P-PAK1 protein levels of SKOV3-PM4 cells significantly decreased compared with the control group , and the group of Rac1 inhibi-tor plus Rhein treatment, the phosphorylated protein decreased more significantly ( P <0. 05 ) . After Rac1 activator plus Rhein treatment, phosphorylated protein expression of P-LIMK1 ,P-PAK1 and P-cofilin upregu-lated significantly ( P <0. 05 ) . Conclusions Rhein may be a potential inhibitor of Rac1 and can inhibit the migrating and invasive capabilities of directional high lymphatic metastasis SKOV3-PM4 cells through down-regulating the phosphorylation of Rac1/LIMK1 /cofilin pathway associated protein.

Objective To investigate the dynamic change and the clinical curative effect evaluation of plasma (1-3)-beta glucan D (BG) in the patients with pulmonary disease complicating fungal infection .Methods The MB-80 miroorganism dynamic rapid de-tection system and fungi BG detection kits were adopted to detect plasma BG content before and after treatment in 87 cases of pul-monary disease complicating fungal infection and the controls .The sputum culture in the patients was performed before and after treatment .Results Plasma BG levels before antifungal therapy ,at 1 ,2 weeks after treatment in 87 patients were (162 .81 ± 70 .03) , (15 .89 ± 30 .88) and (4 .58 ± 7 .87)pg/mL ,which in the control group was (5 .62 ± 1 .83)pg/mL ,plasma BG level had statistical differences between before treatment and at 1 ,2 weeks after treatment in the patients with the control group (P<0 .05);Plasma BG levels between at 1 week after treatment with at 2 weeks after treatment and the control group had statistically significant differ-ences (P<0 .05) .Among 87 patients ,66 cases were positive sputum culture at 1 week after antifungal drug treatment and 9 cases were positive sputum culture at 2 weeks after treatment .Conclusion Continuously monitoring the patient′s plasma BG level com-bined with the sputum fungal culture results ,clinical symptoms and lung shadow in X-ray has certain clinical value to judge the anti-fungal effect .

OBJECTIVETo explore the distribution of monoamine oxidase A (MOA-A) EcoRV polymorphism in Shanghai Han population and its possible role in the risk for Parkinson's disease(PD).
METHODSThe MAO-A gene EcoRV polymorphism was detected with PCR-RFLP method in 110 PD patients and 182 healthy controls, furthermore, statistical analysis was performed to investigate association between EcoR V polymorphism and PD onset.
RESULTS(1)Remarkable difference in MAO-A EcoR V polymorphic distribution has been observed between Shanghai Han population and that in North America. (2) Neither allelic frequency nor genotypic frequency in PD cases differs significantly from that in healthy controls regardless of data from male or female subclass.
CONCLUSIONThere may be racial difference in the distribution of the human MAO-A EcoR V (C/T) polymorphism, but the present research does not support the association between this variant and susceptibility to PD in Chinese Han population of Shanghai area.
