Objective　To array the small intestine so that the uncontrollable adhesions will turn to controllable abhesions in order to prevent the intestinal obstruction. Methods　Literatures were reviewed. The advance of plication of small intestine has passed through three stages: 1st, sewing the intestine just like the array of harpsichord keys; then, using straight needle with coarse threads to make a 'U' suture for the mesentery of small intestine so the intestine was arrayed, and 3rd inserting a Millers-Abbott tube into the lumen of small intestine followed by manual arrangement of the intestine. Results　Using the Millers-Abbott tube the intestine was fixed in a steady position and arrayed in a half moon circular shape to avoid sharp angle. As a result, the intra-luminal pressure of the intestinal was effectively decreased. Follow up 45 cases showed the cure rate of 91.9%. Conclusion　This operation has widely been accepted by the surgeons for its simplicity, high efficacy and reliability. It reduces the recurrence rate of adhesive obstruction.

Objective To investigate the relevance between relapse and course of treatment in genotype 1 chronic hepatitis C (CHC)pa-tients with slow virologic response.Methods Totally 157 genotype 1 CHC inpatients or outpatients were selected from the Third People′s Hospital of Jiaozuo and the People′s Hospital of Jiaozuo from April 2010 to March 2013.The patients were treated with interferon α-1b in conjunction with ribavirin.At 6 months of the initial treatment,5 1 patients with slow virologic response were randomly divided into groups A (24 cases)and B (27 cases),which received continued treatment for another 6 and 12 months,respectively.A 1 -year follow-up of pa-tients was performed after withdrawal of treatment.Adverse reactions in patients receiving the antiviral therapy were assessed.Furthermore, group comparisons were performed on the clearance rate of hepatitis C virus (HCV)RNA and normalization rate of alanine aminotransferase (ALT)at withdrawal of treatment,as well as the CHC relapse rate and ALT normalization rate at 6 months and 1 year after withdrawal of treatment.Continuous data were compared using t test,and categorical data were compared usingχ2 test.Results The rate of adverse reac-tions in patients receiving antiviral therapy had no significant difference between groups A and B (P>0.05 ).At withdrawal of treatment, there were no significant differences between groups in terms of HCV RNA clearance rate (95.65%vs 92.59%)and ALT normalization rate (95.65% vs 88.89%)(χ2 =0.02 and 0.13,respectively,both P>0.05).At 6 months and 1 year after withdrawal of treatment,the CHC relapse rate in group B was significantly lower than that in group A (20.00% vs 50.00%,χ2 =4.69,P <0.05;36.00% vs 68.18%,χ2 =4.85,P<0.05);the ALT normalization rate in group B was nonsignificantly higher than that in group A (84.00% vs 59.09%,χ2 =3.63,P>0.05;72.00% vs 50.00%,χ2 =2.40,P>0.05).Conclusion To extend the 6 -month course of treatment can significantly reduce the relapse following slow virologic response in patients with genotype 1 CHC.

Objective To study the relation between the pressure in forefoot and the second metatarsalgia in hallux valgus deformity, finally to quantitatively analyze the pressure under the second metatarsal head which is a dangerous factor leading to second metatarsalgia. Methods Three groups volunteered for this study by a self-devised foot pressure measurement system: fifty-eight normal subjects (116 feet) without pain and deformity in foot, thirty-two patients (45 feet) with hallux valgus and pain only under the second metatarsal head, fifty-six patients (102 feet) with hallux valgus without symptoms of metatarsalgia. The percentage of pressure to weight was the criteria for data analysis. First the pressures under second metatarsal head among three groups were compared with each other. Secondly we used case-control study to identify whether it was high pressure that was likely to result in metatarsalgia. Finally we compared the pressure interval under second metatarsal head among three groups to define the pressure interval which might be a dangerous factor to second metatarsalgia. Results 1)The pressure beneath the second meatatarsal head in patients with metatarsalgia was the highest in the three groups (P
