Red cell deformability in diabetics is much lower than that in normal controls. In patients with diabetic retinopathy, the decrease of red cell deformability is much more prominent than in patients without. Urinary albumin excretion rate in diabetic patients is inversely correlated with red cell deformability .The data above suggest that there is a close relationship between decreased red cell deformability and microangtopathy in diabetic patients

Objective To analyze the clinical value of microRNAs applied in the early diagnosis of pancreatic cancer.Methods The expression of mir-155,mir-196a,mir-181a,mir-181b in three pancreatic cancer cell lines PANC-1,PaCa-2,AsPC-1 pancreatic cancer,normal pancreatic cells and plasmas of 100 patients with pancreatic cancer ,100 normal volunteers were detected by Real-time PCR,and the results were analyzed.The expression of mir-155,mir-196a,mir-181a,mir-181b in 100 pancreatic cancer tissues and 100 normal pancreatic tissues were detected by immunohistochemical,and the results were analyzed. Results Real-timePCR test results showed that compared with normal pancreatic cells,mir-155,mir-196a expression in three pancreatic cancer cells PANC-1,PaCa-2,AsPC-1 were significantly increased(P<0.05).Compared with healthy volunteers,mir-155,mir-196a,mir-181a,mir-181b expression of plasma in pancreatic cancer patients were significantly higher(P<0.05).Immunohistochemistry results showed that mir-155,mir-196a mir-181a and mir-181b expression in pancreatic tissue were significantly higher than that in normal pancreatic tissue (P <0.05 ).Conclusion The expression of mir-155,mir-196a,mir-181a and mir-181b are high in pancreatic cancer tissues and pancreatic cancer cell lines,which are closely related to the development of pancreatic cancer.Those microRNAs are expected to be cancer markers for early diagnosis of,pancreatic cancer,have highly diagnostic value and broad clinical application.

Objective To study the relationship between the co‐expression levels of inducible costimulatory molecule (ICOS)and CD28 on peripheral blood CD4+ and CD8+ T cells and Behcet’s disease(BD).Methods Flow cytometry was used to detect the expression levels of ICOS and CD28 on peripheral blood CD4+ and CD8+ T cells of BD patients(n=22) ,including those with active BD(ABD ,n= 14)and stable BD(SBD ,n= 8) ,and of normal subjects(n= 22).Results The proportion of CD28+ ICOS+ CD4+ T cells was significantly increased in ABD patients when compared with normal subjects [(34.72 ± 12.87)% vs.(25.36 ± 8.24)% ,P<0.05].No significant difference was found in the proportion of CD28+ ICOS+ CD8+ T cells [(9.32 ± 4.57)% vs.(7.24 ± 3.36)% ,P>0.05]between the two groups.The proportions of CD28-ICOS+ CD4+ T cells and CD28-ICOS+CD8+ T cells were both obviously increased in ABD patients when compared with those in normal subjects[(2.54 ± 1.63)% vs.(0.76 ± 0.25)% for CD28- ICOS+ CD4+ T cells ,P< 0.05;(8.79 ± 3.41)% vs.(3.04 ± 1.25)% for CD28-ICOS+CD8+ T cells ,P<0.05].Conclusion The increased expression level of ICOS on peripheral blood CD4+ and CD8+ T cells is not closely associated with the expression of CD28 to some extent in BD patients ,suggesting that cells expressing only ICOS play an important role in the development of BD.

Objective To detect the expression of macrophage inlfammatory protein 1α(MIP-1α) in the myocardium of viral myocarditis (VMC) mice at different phases. Methods A total of 120 4-week-old male BALB/c mice were randomly divided into 2 groups, 80 in the VMC group and 40 in the control group. Mice in VMC group were inoculated intraperitoneally with coxsackievirus B3 to build VMC models, while mice in control group were treated with DMEM cultivate liquid. Ten mice of each group were sacriifced on days 3, 7, 15 and 30 after treatment and their heart tissues were collected for analysis. The level of MIP-1αin the myocardium was determined by immunohistochemistry. Myocardial histopathology was examined with hematoxylin and eosin stain. In addition, the relationship between the level of MIP-1αand the degree of myocardial lesion was investigated. Results The expression of myocardial MIP-1αprotein in VMC group was up-regulated in myocardium on day 3 after inoculation of virus, and slowly decreased after the peak on day 7, but still sustained a high level on day 30. Compared with the control group, the levels of MIP-1αin VMC group were increased signiifcantly at every phase (P<0.05). Furthermore, positive correlation was found between MIP-1αprotein expression levels and myocardial histopathologic scores in VMC group (r=0.94, P<0.01). Conclusion The up-regulated expression of MIP-1αmay play a critical role in the pathogenic mechanisms of viral myocarditis.

Objective To study the clinical effects of breast-preserving surgery in early-stage breast cancer. Methods From March 2002 to March 2007, 27 cases of early-stage breast cancer were treated with breast-preser-ving surgery. The control group had 28 cases, treated with radical mastectomy. Survival rate and recurrence rate were observed. Results The short-term progress of breast-preserving surgery in early-stage breast cancer had no significant difference with that of radical mastectomy. Plastic effects of breast were satisfied. Conclusion Breast- preserving surgery in early-stage breast cancer had favorable effects both in progress and in plastic. Therefore, it is warranted for wide use.

Objective To investigate the clinical value of peri-interventional procedure serum bile acid(TBA)detection in patients with primary liver cancer. Methods The serum TBA was examined peri-operatively in 160 patients with primary liver cancer for testing the correlations between TBA, liver function, the degree of hepatocirrhosis, interventional therapy method and hepatic failure. Results The preoperative mean value of serum TBA incseased significantly in comparing with that of the control group (P
