Objective To observe the effect of gastrectomy for gastric cancer on blood glucose in patients complicated with type 2 diabetes mellitus by using different operation strategies.Methods The retrospective analysis was carried out of 68 cases who undergone radical surgery for gastric cancer and complicated with type 2 diabetes mellitus.These patients were divided into 3 groups by different kinds of digestive tract reconstruction,Billroth Ⅰ (n =26),Billroth Ⅱ (n =22) and Roux-en-Y (n =20).The levels of fasting blood glucose (FBG) were detected before and after operation one week,one month and six months in three groups.Results Comparing to the level before operation,the level of FBG after operation showed a descent in group B and group C((10.03 ±5.12) vs.(13.56 ±3.36) mmol/L; (8.44 ±5.21) vs.(13.56 ±3.36) mmol/L;(10.61 ±3.16) vs.(12.84 ±3.36) and(7.68 ±4.88) vs.(12.84 ±3.36) mmol/L) which was better than group A((10.03 ±5.12)vs.(11.12 ±6.32),(8.44 ±5.21) vs.(11.12 ±6.32) mmol/L;(10.61 ±3.16) vs.(11.12 ±6.32) mmol/L),(7.68 ±4.88) vs.(11.12 ±6.32) mmol/L;P＜0.05,but there was no significantly difference between B and group C (P ＞ 0.05).The 3 groups of patients,with B,C groups of patients with diabetes improved obviously,of which nearly 50％ of patients cured,normal blood sugar control,the other part with the exception of a few effective,degradation of diabetes drug treatment,and operation effect was significant.Conclusion It is effective to control the blood glucose of gastric cancer patients complicated with type 2 diabetes with Billroth II or Roux-en-Y gastrectomy.There is a correlation between postoperative blood glucose change and different gastrojejunal anastomosis.

Objective To explore the efficacy and complication of total hip arthroplasty in the treatment of ankylosing spondylitis hip joint ankylosis,and analyze its prognosis.Methods Eighty-two patients with ankylosing spondylitis hip joint ankylosis were divided into observation group and control group by random digits table method,the 42 patients in observation group were given total hip arthroplasty after the diagnosis of early,the 40 patients in control group were given delayed total hip arthroplasty.In the 2 groups,the recovery of hip joint function were observed,postoperative complication were recorded,and the 5-year survival rate situation were followed up.Results The activity of hip joint,degree of hip joint flexion and Harris score after operation in the 2 groups were significantly better than those before operation,there were statistical differences (P ＜ 0.05),the indexes after operation in observation group were significantly better than those in control group [activity of hip joint:175.25° ± 15.52° vs.122.95° ± 16.26° ; degree of hip joint flexion:85.65° ± 5.33° vs.70.78° ± 4.97° ;Harris score:(86.08 ± 5.41) scores vs.(73.92 ± 6.62)scores],there were statistical differences (P ＜ 0.05).Infection occurred in 1 case,dislocation in 0 case,prosthesis loosening in 2 cases in observation group,the rate of complication was 7.14％(3/42).Infection occurred in 5 cases,dislocation in 2 cases,prosthesis loosening in 4 cases in control group,the rate of complication was 27.50％ (11/40).The rate of complication in observation group was significantly lower than that in control group,there was statistical difference (x2 =8.34,P＜ 0.01).The 1,3-year survival rate in observation group was higher than that in control group,but there was no statistical differences (P ＞ 0.05).The 5-year survival rate in observation group was significantly higher than that in control group [90.48％(38/42) vs.70.00％ (28/40)],there was statistical difference (x2 =7.57,P ＜ 0.01).Conclusion Early total hip arthroplasty has significantly clinical effects in the treatment of patients with ankylosing spondylitis hip joint ankylosis,and its early operation curative effect is better than that of delayed operation.

Kenaf has a high content of gum that is difficult to remove. Traditional chemical degumming process causes serious environmental pollution. To solve the problem, we developed a new method to degum kenaf. We pretreated the kenaf with steam explosion followed by ultrasonic treatment. We chose the single factor tests to select the ultrasonic frequency, sodium hydroxide concentration and processing time. Combined with orthogonal tests, we found that the optimum conditions were as follows: ultrasonic frequency was 28 kHz, sodium hydroxide concentration was 2%, and processing time was 60 min. Under these conditions, the residual gum of kenaf fiber was 9.72% and the fineness was 139.45 N(m). Steam explosion combined with ultrasonic method is effective in degumming of kenaf.

Objective To explore the clinical effect of tension-free repair in the treatment of inguinal hernia in elderly patient.Methods A total of 124 elderly patients with inguinal hernia admitted in our hospital in 2016 were randomly divided into a study group(n=62)and a control group (n=62).The control group was treated with open tension-free inguinal hernia repair,whereas with laparoscopic tension-free inguinal hernia repair in the study group.The operation time,intraoperative blood loss,the postoperative pain relief-time,mean days of hospitalization,postoperative recurrence rate,and complications rates were compared between the two groups.Results The more significant improvements were found in study group versus control group in the intraoperative bleeding volume [(19.9±2.0)ml vs.(36.8±-2.5)ml,t=41.564,P=0.000],in the mean hours of postoperative pain [(22.1 ± 4.2) h vs.(35.3 ± 7.0) h,t =12.732,P =0.000],in mean days of hospitalization [(5.5 ± 1.0)d vs.(9.2±1.9)d,t=13.569,P=0.000],in incidence rate of postoperative recurrence(0.0％ vs.6.5％,x2 =4.133,P=0.042),and in postoperative complications rate(3.2％ vs.12.9％,x2 =3.916,P=0.048).Nevertheless,the operation time was longer in the study group than in the control group[(87.0±5.0)min vs.(55.5±4.2)min,t=-37.984,=0.000],Conclusions As compared with open tension-free repair,the clinical efficacy of laparoscopic tension-free hernia repair is exactly sure in the treatment of inguinal hernia,with shorter postoperative hospitalization time and lower incidence of complications.
