Objective To observe the clinical efficacy of atorvastatin combined with sodium ferulic acid on renal interstitial fibrosis of diabetic nephropathy(DN).Methods According to the diagnostic and staging criteria of DN,56 patients of DN(Mogensen stage Ⅲ~Ⅳ)who hadn’t received lipid-lowering treatment in the last 2 months and glycemic control were within the standard were randomly divided into control group (n =28 )and experimental group(n=28).Control group were received basic treatment including diabetes diet,decreasing blood glucose level and adjusting blood pressure.Experimental group were added atorvastatin combined with sodium besides the basic treatment above-mentioned.The course is both 4 weeks in two groups.Changes of fasting plasma glucose(FPG),blood urea nitrogen(BUN),serum creatinine(SCr)and 24-hour urine albumin excretion rate (24hUAER),transforming growth factorβ1 (TGF-β1 )before and after the treatment in two groups were observed. Results The differences of FPG,BUN, SCr,24h UAER and TGF-β1 in two groups before and after treatment were statistically significant(P<0.01).Conclusion Atorvastatin combined with sodium ferulate can function cooperatively in the treatment of diabetic nephropathy and can delay renal interstitial fibrosis.

Objective To compare and analyze the changes of CEA,CA19-9,CA72-4 in different pathologictypes of gastric cancer.Methods 93 patients with gastric cancer were divided into different groups according to the histological types,pathologic types and TNM staging.The levels of CEA,CA19-9,CA72-4 of the patients were measured,then the results were compared and analyzed.Results The level of serum tumor marker of the moderately differentiated group was obviously higher than that of well-differentiated group(P ＜ 0.05),while the level of serum tumor marker of the poorly differentiated group was obviously higher than that of moderately differentiated group (P ＜ 0.05).The differences of levels of CEA,CA19-9,CA72-4 between the well-differentiated group,moderately differentiatedgroup and poorly differentiated group were statistically significant(F =61.433,57.882,125.547,all P ＜ 0.05).The differences of levels of CEA,CA19-9,CA72-4 between patients of TMN Ⅰ stage,TMN Ⅱ stage,TMN Ⅲ stage,TMN Ⅳstage were statistically significant(F =189.624,95.236,80.342,all P ＜ 0.05).The difference of serum tumor marker between different histological groups was not statistically significant (all P ＞ 0.05).Conclusion The concentration of serum CEA,CA19-9,CA72-4 will be higher if the gastric tumor is poorly differentiated or invades deeply,but the concentration of serum tumor has nothing to do with the histological types of the tumor.

Objective To study the application of carcinoembryonic antigen (CEA),carbohydrate antigens19-9 (CA19-9) and carbohydrate antigens72-4 (CA72-4) in the diagnosis of gastric cancer.Methods A total of 78 patients with gastric cancer underwent treatment in our hospital from August,2007 to June,2011 were enrolled as the case group.A total of 78 patients with benign gastric diseases and 78 healthy residents of the same period and district were randomly selected as the benign group and healthy control group,respectively.Measurements of serum CA72-4,CA19-9,CEA of all the cases and control group were performed.And the measurements of the three groups were statistically compared.Results The Serum concentration of CA72-4,CA19-9,CEA were significantly higher than the other two groups [CEA:(27.56 ± 18.36) μg/L vs (2.44 ±0.97) μg/L vs (2.37 ± 1.25) μg/L,F =145.346,P ＜0.0001 ; CA19-9:(99.87 ±80.53) kU/L vs (18.21 ±10.36) kU/Lvs (17.48 ±9.66) kU/L,F=78.503,P＜0.0001; CA72-4:(56.13 ±39.26)kU/L vs (5.77 ±2.95) kU/L vs (3.62 ±2.18) kU/L,F =133.892,P ＜0.0001].And the positive rate of the gastric cancer group were significantly higher than those of the other two groups [CEA:69.23％,10.26％and 7.69％; CA19-9:57.69％,23.07％ and 20.51％; CA72-4:83.33％,10.26％ and 8.97％].The combination of the 3 measurements obtained the highest accuracy of diagnosis,while for single measurement,CA72-4 had the highest accuracy.Conclusion CEA,CA19-9 and CA72-4 have a significant meaning in the early diagnosis of gastric cancer,which has high sensitivity and specificity.The detection rate of the gastric cancer will be improved if the test of CEA,CA19-9 and CA72-4 are combined.

Objective To evaluate the myocardial protective effects of pinacidil combined with pyrrolidine dithiocarbamate (PDTC) against ischemia-reperfusion (I/R) injury to the isolated rabbit hearts and investigate its mechanisms. Methods One-hundred and twelve Japanese long-ear white rabbits of both sexes weighing 1.8-8.2 kg were killed by a knock to the head after heparinization. Their hearts were immediately removed and mounted on Langendorff apparatus and perfused with oxygenated K-H solution at 371 . Of the 112 isolated hearts 96 were randomized into 6 groups with 16 hearts in each group of which 8 hearts underwent 60 min reperfusion and another 8 hearts 120min reperfusion after 40min global myocardial ischemia: the hearts were perfused with K-H solution in group Ⅰ(K); with St Thomas Ⅱ solution in group Ⅱ(S); with pinacidil in group Ⅲ(P); with PDTC + K-H solution in group Ⅳ(PK); with PDTC + St Thomas Ⅱ solution in group Ⅴ(PS) and with PDTC + pinacidil in group Ⅵ(PP) . The rest of the 112 hearts (16 hearts) were perfused with K-H solution for 10 min. Then myocardial tissue was obtained for immuno-histochemical examination (SABC staining) used as normal control value.(1) Time of resumption of heart beat (from the beginning of reperfusion to the resumption of heart beat) was recorded; (2) left ventricular systolic and end-diastolic pressure (LVSP, LVEDP) and + dp/dtmax were monitored; (3) effluent from coronary sinus was collected at 60 min of reperfusion for determination of TNF-? concentration and (4) myocardial tissue was obtained at the end of reperfusion for determination of expression of NF-?B p65 and ICAM-1 in myocardium. Results (1) The heart beat resumption time was significantly shorter in group PP, PS and P than in the other 3 groups (P

Objective To study the relationship between the T helper cells (Th22)/interleukin (IL)-22 and rheumatoid arthritis (RA) with interstitial lung disease (ILD), and to define the clinical significance of Th22 cells for RA. Methods The quantity of Th22 cells in the peripheral blood from 40 patients with RA (20 RA with ILD, 20 RA without ILD) were examined by flow cytometry, the level of IL-22 in the sera was detected by enzyme-linked immunosorbent assay (ELISA). Comparisons between groups were analyzed by t-test, rank sum test, and the correlation of parameters were tested by linear correlation analysis. Results The quantities of CD4+IL-22+ cells (Th22) in RA patients [(0.15 ±0.07)%] were significantly higher than normal controls [(0.09 ±0.05)%] (t=4.097, P<0.01), and IL-22 levels in RA patients [(83 ±7) ng/L] were significantly higher than normal controls [(61±5) ng/L] (t=13.057, P<0.01). The quantities of Th22 cells in RA-ILD patients [(0.18±0.07)%] were significantly higher than RA-NILD patients [(0.13±0.05)%] (t=2.919, P=0.008), and IL-22 levels in RA-ILD patients [(87±6) ng/L] were significantly higher than RA-NILD patients [(80±6)ng/L] (t=3.624, P=0.001). The quantities of Th22 cells were positively correlated with erythrocyte sedimentation rate (ESR), rheumatoid factor(RF) and 1.4 disease activity score (DAS)28 (r=0.336, 0.377, 0.577, P<0.05),and the level of IL-22 were also positively correlated with ESR and DAS28 (r=0.406, 0.576, P<0.05). Conclusion The quantities of Th22 cells and IL-22 level are increased in RA patients, especially in RA-ILD patients. The quantities of Th22 cells and IL-22 level are positively correlated with ESR and DAS28. It may play a certain role in RA especially in RA with ILD.
