Objective To investigate the effect and safety of alprostadil in the treatment of diabetes complicating chronic kid‐ney disease to provide reference for clinical treatment .Methods 84 cases of diabetes complicating chronic kidney disease in this hospital from September 2013 to January 2015 were selected and divided into the observation group(44 cases) and the control group (40 cases) according to the voluntary principle .The control group used the epalrestat treatment ,while the observation group was combined with using alprostadil on the basis of control group .The effective rate ,serum creatinine ,blood urea nitrogen(BUN) ,uri‐nary albumin excretion rate ,C‐reactive protein(CRP) ,IL‐6 levels and adverse reactions were compared between the two groups .Re‐sults The effective rate of the observation group was 93 .18% ,which was significantly higher than 80 .00% in the control group , the difference was statistically significant (χ2 =4 .251 ,P=0 .005);the CRP and IL‐6 levels after treatment in the observation group were improved ,the difference was statistically significant (P<0 .05);the CRP and IL‐6 levels after treatment in the observation group[(0 .45 ± 0 .05)mg/L ,[(0 .72 ± 0 .11)μg/L] were significantly superior than[(1 .05 ± 0 .14)mg/L ,(1 .25 ± 0 .24)μg/L] in the control group ,the differences were statistically significant(P<0 .05);BUN ,urinary albumin excretion rate ,TNF‐αand endogenous creatinine clearance rate after treatment in the observation group were (6 .41 ± 1 .12)mmol/L ,(41 .12 ± 4 .46)μg/min ,(75 .54 ± 6 .64)ng/L and (92 .94 ± 8 .24)% ,which in the control group were (7 .39 ± 1 .05)mmol/L ,(91 .48 ± 7 .31)mmol/L ,(111 .42 ± 7 .69)ng/L and (81 .55 ± 9 .54)% respectively ,the improvement in the observation group was better than the control group ,the difference was statistically significant (P<0 .05);the occurrence rate of adverse reactions was 18 .18% in the observation group and 17 .50% in the control group ,showing the difference was not statistically significant (P>0 .05) .Conclusion Alprostadil in treating diabetes complicating chronic kidney disease has better effect ,conduces to improve the level of urinary albumin and inflammatory with high safety ,and is worthy of clinical promotion and application .

Objective To investigate the value of double-balloon enteroscopy and CT enterography for the diagnosis of intestinal Crohn disease ( CD ) . Methods Data of 125 patients with suspected CD undergoing double-balloon enteroscopy and CT enterography were reviewed. Diagnosis was made based on pathological,endoscopic findings and clinic follow-up results. Detection rates and diagnostic rates of double-balloon enteroscopy and CT enterography for intestinal CD were compared. Results The detection and diagnostic rates of intestinal CD by double-balloon endoscopy were 62. 4％( 78/125) and 94. 8％ ( 74/78) , respectively. The sensitivity, specificity and accuracy of double-balloon enteroscopy in the diagnosis of intestinal CD were 100. 0％, 92. 2％ and 96. 8％, respectively. The detection and diagnostic rates of intestinal CD by CT enterography were 44. 8％( 56/125 ) and 89. 3％ ( 50/56 ) , respectively. The sensitivity, specificity and accuracy of CT enterography in the diagnosis of intestinal CD were 67. 6％, 88. 2％ and 76. 0％, respectively. Both the detection rate and the diagnostic rate of double-balloon enteroscopy in intestinal CD were higher than those of CT enterography. Conclusion Double-balloon enteroscopy shows high application value for the diagnosis of intestinal CD, but CT enterography before enteroscopy can guide the selection of endoscopic approach, reduce economic expenditure and alleviate patients' pain, so CT enterography could be the first choice for intestinal CD patients with contraindications of enteroscopy.
