5.Diagnosis of diabetic nephropathy
Chinese Journal of Practical Internal Medicine 2001;0(05):-
Diabetic nephropathy (DN) is one of the chronic diabetic complications,which often leads to chronic renal failure.The diagnosis of DN involves a comprehensive assessment of clinical,pathological and other manifestations.Early diagnosis is rather important for the prevention of DN.

Objective To investigate the impact of hypoxia on the expression of early growth response-1 (Egr-1) and monocyte chemoattractant protein-1 (MCP-1) in mouse aorta,and to probe the underlying mechanism involving receptor for advanced glycation end-products (RAGE).Methods 3-month-old C57BL/6 mice were subjected to hypoxia [(6.0±0.5) % oxygen] to establish the global hypoxia model(n=6 rats for each).Aortas were dissected,Egr-1 mRNA and MCP-1 mRNA were detected by real time RT-PCR,Egr-1 and RAGE proteins were tested by Western blot,and Egr-1 DNA binding activity was assayed by electrophoretic mobility shift assay (EMSA).For blockade of RAGE,mice were pretreated with soluble RAGE (sRAGE) for 1 h by intra-peritoneal injection before they were exposed to hypoxia.Mice with normoxia were used as controls.Results After 30 minutes of hypoxic exposure,Egr-1 mRNA in aorta was increased to (28.3±0.9)folds compared with normoxic controls (F=617.17,P<0.01),and the induction persisted for at least 3 hours.After 45 minutes of hypoxic exposure,Egr-1 proteins in aorta was increased to (5.7 ± 0.3) folds compared with normoxic controls (F =57.18,P< 0.01); the enhanced DNA binding activity of Egr-1 by hypoxia was attenuated by pretreatment with anti-Egr-1 lgG.After 4 hours of hypoxic exposure,MCP-1 mRNA expression in aorta was increased to(4.0±0.3)folds compared with normoxic controls (F=30.68,P<0.01).RAGE antigen was increased significantly within 30 minutes of hypoxic exposure,with the peak at 15 minutes; hypoxia-induced Egr-1 mRNA expression was significantly attenuated by pretreatment with sRAGE (3.3 ± 0.2) folds compared with normoxic controls (F =30.20,P<0.01).Conclusions Hypoxia significantly induces Egr-1 and MCP-1 upregulation expressions in mouse aorta,and blockade of RAGE significantly attenuates hypoxia-induced Egr-1 expression.Thcsc findings suggest RAGE signaling is involved in hypoxia-induced vascular inflammatory stress,and highlight this receptor as a potential therapeutic target to protect tissues injured by hypoxia.

Objective:To investigate the role of anaphylatoxin C 5 a in patients with asthma .Methods:A prospective study was performed between September 2006 and February 2007.A total of 33 patients with acute exacerbation of asthma and 13 healthy subjects were recruited into the study .The patients with acute exacerbation of asthma were also studied when they returned to the remission state .Levels of lung function, levels of C5a in induced sputum and cell differential count in induced sputum were determined . Results:The level of C5 a in induced sputum was significantly higher in patients with acute exacerbation of asthma [0.85(0.68-2.13) μg/L] than that in patients with stable asthma [0.45(0.26-0.88)μg/L, Z=-2.193, P=0.013];Sputum C5a levels in stable asthma patients were significantly higher than those in healthy controls [0.14(0.06-0.45) μg/L, Z=-2.141, P=0.015].The level of C5a in patients with severe exacerbation [2.21(1.27 -9.0) μg/L] was significantly higher than those in patients with mild exacerbation [0.34(0.17-0.63) μg/L] and moderate exacerbation [0.85(0.55-1.67) μg/L,χ2 =12.330, P=0.001].The level of C5a in induced sputum was positively correlated with the number of total cells count (r=0.797, P=0.004), neutrophils (r=0.504, P=0.032) and macrophages ( r =0.424, P=0.036 ) in acute exacerbation of asthma .Conclusion: C5a levels in induced sputum could be identified as an important prognostic biomarker , which involved in asthma ’ s pathogenesis .

To clone the differential genes in antibiotic resistence Neisseria gonorrhoeae,the library that contains the fragments of differential genes between antibiotic resistance strain and standard reference strain of Neisseria gonorrhoeae was constructed which used suppression subtractive hybridization technique. Then the antibiotic resistance relational genes fragments were cloned and analyzed. Antibiotic resistance Neisseria gonorrhoeae subtractive library that has high subtractive efficiency was set up successfully. The amplified library contained 2500 positive clones. Sequence analysis was performed to find the fragments of antibiotic resistance relational genes. Five sequences were unknown previously. The fragments of antibiotic resistance genes may provide an important clue for studying the mechanism of occurrence and development of antibiotic resistance Neisseria gonorrhoeae.

Objective To evaluate the curative effect of chemotherapy combined with radiotherapy for limited-stage small cell lung cancer(LD-SCLC).Methods 34 cases of patients with LD-SCLC were rand- mized into interdigitating chemoradiotherapy group and sequential chemoradiotherapy group.All patients re- ceived four to six cycles of alternating CE(C:carboplatin 300 mg/m~2 d_1;E:etoposide100 mg d_(1~5)and CAP(C: cyclophosphamide 600 mg/m~2 d_(1,8);A:adriamycin 40 mg/m~2 d_1;P:cisplatin 50 mg d_(3~5)chemotherapy,three weeks for a cycle.All patients also received thoracic radiotherapy with conventional fraction,2.0 Gy per frac- tion,five fractions per week.The total dose was 60 Gy.Results In interdigitating chemoradiotherapy group, CR was 64.7%,PR was 29.4%,NR was 5.9% and PD was 0 after chemo-radiation therapy.In sequential chemoradiotherapy group,CR was 23.5%,PR was 52.9%,NR was 23.5% and PD was 0 after chemothera- py,and CR was 58.8%,PR was 35.3%,NR was 5.9% and PD was 0 after radiotherapy.Conclusion The therapeutic effect of chemotherapy combined with radiotherapy for LD-SCLC was satisying.There was no sig- nificant difference in the effect between the two groups.
