Objective To investigate the correlation of homoeysteine (Hcy) and blood glucose level with type 2 diabetic fundus lesions.Methods Sixty patients with type 2 diabetic fundus lesions were selected and grouped as the diabetic fundus lesions group from February of 2011 to October of 2012,and 40 patients with type 2 diabetes were recruited as the diabetes group,40 healthy volunteer were recruited as the control group.Glycosylated hemoglobin Alc(HbAlc),fasting blood glucose(FBG),homocysteine(Hcy) and total cholesterol (TC),triglyceride (TG),high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) of the three groupwere measured and compared.Results Compared with the control group,Hcy in the diabetic fundus lesions group and the diabetic group were significantly higher than the control group ((17.6 ± 4.7) μmol/L,(13.3 ± 2.9) μmol/L vs.(7.3 ± 1.8) μmol/L),and as well as HbA1 c ((11.3 ±2.7)％,(9.2±1.4)％ vs.(4.0±1.1)％),FBG ((11.5 ±3.4) μmol/L,(10.1 ±2.1) μmol/Lvs.(4.2 ±1.7) μmol/L)and TC((6.7 ±1.1) mmol/L,(5.1 ±1.0) mmol/L vs.(4.4±0.8) mmol/L) (F=5.091,5.107,6.017,5.813,P =0.043,0.036,0.032,0.040 respectively).The Hcy,TC,TG,FBG and HbAlc of type 2 diabetic fundus lesions with I stage were the lowest,and the stage of type 2 diabetic fundus lesions was relevant with the level of Hcy,TC,TG,FBG and HbAlc,which were different significantly (F =5.418,5.524,4.971,5.713 respectively,P =0.038,0.041,0.042,0.040 respectively).Conclusion The serum Hcy and blood glucose are risk factors to type 2 diabetic nephropathy.Lowering Hcy concentration and reducing the glucose may be a new way to prevent the occurrence of type 2 diabetic nephropathy.

Objective To investigate the correlation of PARP with the metastasis of colorectal carcinoma.Methods Poly(ADP-ribose) polymerase activity was tested by detecting poly-ADP ribose.Immunohistochemical SP was used to detect the expression of PAR,P-selectin and ICAM-1 in colorectal carcinoma and control colorectal mucosa.The co-expression of PAR with P-selectin and ICAM-1 was investigated by immunofluorescence staining in colorectal carcinoma and control colorectal mucosa.Results The expression of PAR,P-selectin and ICAM-1 was significantly higher in colorectal carcinoma than that in the control colorectal mucosa((P

Objective To investigate the gene mutation of epithelial growth factor receptor(EGFR) and the expressions of hu‐man epiderma1 growth factor receptor 2(HER‐2) and vascular endothelial growth factor(VEGF) in lung adenocarcinoma and their relationships with the clinical pathological factors .Methods ARMS‐PCR method was used to detect the gene mutation of EGFR in 49 lung adenocarcinoma specimens and 10 normal tissue specimens .Immunohistochemical method was also used to detect the ex‐pressions of the HER‐2 and VEGF in them .Results (1) The mutation rates of EGFR and the positive rates of HER‐2 and VEGF in lung adenocarcinoma were significantly higher than those in the normal tissues(P< 0 .01) .(2) The occurs of EGFR mutation were correlated with sex and the smoking habit(P<0 .05);but not correlated with age ,the size of tumor ,differential ,lymph nodes metastasis ,TNM stages and pleural invasion(P>0 .05) .The HER‐2 and VEGF protein expressions in lung adenocarcinoma were correlated with differential ,the size of tumor ,TNM stages ,lymph nodes metastasis and pleural invasion(P<0 .05);but not correla‐ted with sex ,age ,and the smoking habit(P>0 .05) .(3) The expressions of HER‐2 and VEGF protein in the lung adenocarcinoma were positively correlated with each other(P<0 .01) .Conclusion EGFR mutation is closely related to the occurrence of lung ade‐nocarcinoma ,its high expressions in the women ,non smoking people have important clinical significance .HER‐2 and VEGF could promote the lung adenocarcinoma′s occurrence ,development and transfer .They could be used to evaluate the patients′prognosis ,and provide new molecular targeted therapy .

Objective To explore the influence of irbesartan and metoprolol on the ambula-tory blood pressure of patients with hypertension.Methods 80 patients with primary hypertension were selected and randomly divided into irbesartan group and metoprolol group,40 cases in each group.24 hours ambulatory blood pressure monitoring (ABPM)before treatment and 3 months af-ter treatment was conducted,and pressure control was observed in both groups.Results Before treatment,there was no significant difference of blood pressure between two groups,and blood pressure decreased significantly after treatment,and mean 24 hours diastolic blood pressure (DBP) at night after treatment did not change greatly.There were significant differences of 24 hours sys-tolic blood pressure (SBP),24 hours DBP,SBP and DBP at daytime and night,which decreased much more significantly in irbesartan group than in metoprolol group.Conclusion Irbesartan and metoprolol both have a favorable anti-hypertensive effect on primary hypertension,but irbesartan is more effective.

Objective:To investigate the level and significance of CD4 + CD25 + Foxp3 + Treg in peripheral blood of patients with type 2 diabetes mellitus (T2DM) peripheral neuropathy. Methods:160 patients with T2DM (T2DM group) treated in Yancheng First People's Hospital from January 2018 to March 2019 were selected, including 54 patients with peripheral neuropathy and 106 patients without peripheral neuropathy. At the same time, 160 healthy people were selected as the control group to detect the levels of CD4 + CD25 + Foxp3 + Treg and 25-(OH)D 3 in peripheral blood. Pearson correlation analysis was used to analyze the correlation between CD4 + CD25 + Foxp3 + Treg in peripheral blood and other indexes. The receiver operating characteristic (ROC) value curve was used to analyze the predictive value of CD4 + CD25 + Foxp3 + Treg in peripheral blood of type 2 diabetic peripheral neuropathy. Results:The ratio of CD4 + CD25 + Foxp3 + Treg in T2DM group was (7.82±1.03)%, which was significantly lower than that in control group [(15.53±3.82)%, P<0.05]; The duration of T2DM patients with peripheral neuropathy was (7.71±1.18)years, which was significantly longer than that without peripheral neuropathy ( P<0.05), while the proportions of 25-(OH)D 3 and CD4 + CD25 + Foxp3 + Treg were (49.88±12.27)mmol/L and (5.88±1.20)% respectively, which were significantly lower than that without peripheral neuropathy ( P<0.05); Patients with peripheral neuropathy in group T2DM had significantly higher Michigan Diabetic Neuropathy Scores (MDNS) than that in patients without peripheral neuropathy [(14.82±2.01) vs (4.41±0.43), P<0.05]. The CD4 + CD25 + Foxp3 + Treg was positively correlated with 25-(OH)D 3 ( r=0.367, P<0.05), and negatively correlated with MDNS ( r=-0.398, P<0.05); the CD4 + CD25 + Foxp3 + Treg predicted that the area under the ROC curve of T2DM patients with peripheral neuropathy was 0.822, the cut-off value was 6.50%, and the sensitivity and specificity were 80.00% and 72.00% respectively. Conclusions:The level of CD4 + CD25 + Foxp3 + Treg in peripheral blood of T2DM patients decreased, which may play a role in the occurrence and development of peripheral neuropathy.
