BACKGROUND:There are more ways of internal fixation in treatment of elderly intertrochanteric fracture;however, how to choose a fixed way is the key issue of ensuring the efficacy. OBJECTIVE:To compare the therapeutic effect of proximal femoral anti-rotation intramedul ary nail and proximal femoral locking plate in the treatment of elderly femoral intertrochanteric fractures. METHODS:Total y 100 patients with femoral intertrochanteric fractures who received the treatment at Qionghai City People’s Hospital from December 2009 to December 2013 were randomly divided into locking plate and anti-rotation intramedul ary nail groups. Patients in the anti-rotation intramedul ary nail group underwent internal fixation using proximal femoral anti-rotation intramedul ary nail. Patients in the locking plate group underwent internal fixation using proximal femoral locking plate. RESULTS AND CONCLUSION:Compared with the locking plate group, the amount of bleeding, operation time, postoperative bed activity time and hospital stay in the anti-rotation intramedul ary nail group significantly reduced, the excel ent rate of Harris scores was significantly increased after 1 year of internal fixation and the incidence of complications and adverse reactions was significantly decreased. There was no host response to the material in these two groups.

Objective To investigate the efficacies of laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery in the treatment of patients with different body mass indexes (BMI) and type 2 diabetes mellitus.Methods The clinical data of 40 patients with type 2 diabetes mellitus who underwent LRYGB surgery at the Shengjing Hospital of China Medical University from January 2013 to December 2013 were retrospectively analyzed.According to different BMI,8 patients with BMI ＜ 27.5 kg/m2 were allocated into group 1,14 patients with BMI≥27.5 kg/m2 and ＜32.5 kg/m2 in group 2 and 18 patients with BMI≥32.5 kg/m2 in group 3.Forty patients were followed up via telephone interview and food habits questionnaire by weight loss file managers of Shengjing Hospital and the fourth Affiliated Hospital of China Medical University.All the patients received the reexamination of blood test and data collection at postoperative year 1.The preoperative and postoperative 1-year fasting plasma glucose,glycosylated hemoglobin (HbA1 c),BMI and C-peptide were collected and detected.The fasting plasma glucose ＜ 7.00 mmol/L and HbA1 c ＜ 7.00％ were used as a standard of complete remission.Count data and comparison of rates were analyzed using the chi-square test.Measurement data with normal distribution were presented as x ± s and analyzed by the t test.Skew distribution data were described as M (range) and analyzed by the Wilcoxon rank sum test.Repeated measurement data were analyzed by the repeated measures ANOVA.Results Forty patients received successful LRYGB surgery without perioperative complications,and were followed up for 1 year at the Shengjing Hospital (23 patients),the fourth Affiliated Hospital (8 patients) and other hospitals (9 patients).Of the 40 patients,85.0％ (34/40) of patients had no postoperative long-term obvious malnutrition,anastomotic stenosis,ion disorders and digestive tract dynamic obstacles,15.0％ (6/40) of patients were not adapted to the change of life habits such as frequent nausea and vomiting.Five patients with different degrees of frequent vomiting,abdominal pain and night heartburn within postoperative 1 month had the remission of synptoms after symptomatic treatment.One patient in group 2 had a symptom of hypertonic coma due to intake of oral high-sugar drinks at postoperative 1 week and then was cured by hospitalization.The fasting plasma glucose,HbA1c and BMI in group 1 from preoperation to postoperation were decreased from 11.07 mmol/L (range,6.00-17.00 mmol/L) to 7.18 mmol/L (range,6.00-15.00 mmol/L),from 8.85％ (range,6.00％-11.00％) to 6.35％ (range,6.00％-9.00％) and from 26.0 kg/m2 (range,22.0-27.0 kg/m2) to 22.2 kg/m2 (range,20.0-25.0 kg/m2),with significant differences (F =2.413,3.256,6.750,P ＜ 0.05).C-peptide from preoperation to postoperation was decreased from 1.20 nmol/L (range,1.00-3.00 nmol/L) to 1.07 nmol/L (range,1.00-2.00 nmol/L),with no significant difference (F =1.678,P ＞ 0.05).The remission rate of diabetes in group 1 was 3/8.The fasting plasma glucose and HbA1c in group 2 from preoperation to postoperation were decreased respectively from 10.73 mmol/L (range,7.00-19.00 mmol/L) to 5.89 mmol/L (range,5.00-9.00 mmol/L) and from 8.00％ (range,6.00％-15.00％) to 5.85％ (range,5.00％-8.00％).The BMI from preoperation to postoperation was decreased from 31.0 kg/m2 (range,29.0-32.0 kg/m2) to 25.5 kg/m2 (range,21.0-29.0 kg/m2),with significant differences in the above 3 indexes (F =5.449,4.008,-3.296,P ＜ 0.05).C-peptide from preoperation to postoperation was decreased from 1.53 nmol/L (range,1.00-5.00 nmol/L) to 1.52 nmol/L (range,1.00-6.00 nmol/L),with no significant difference (F =-0.251,P ＞ 0.05).The remission rate of diabetes in group 2 was 10/14.The fasting plasma glucose,HbA1c and BMI in group 3 from preoperation to postoperation were decreased from 9.44 mmol/L (range,5.00-16.00 mmol/L) to 6.65 mmol/L (range,4.00-15.00 mmol/L),from 7.90％ (range,6.00％-11.00％) to 6.45％ (range,5.00％-9.00％) and from 36.9 kg/m2 (range,33.0-47.0 kg/m2) to 27.7 kg/m2 (range,23.0-34.0 kg/m2),with significant differences (F =-3.027,-3.410,-3.724,P ＜ 0.05).C-peptide from preoperation to postoperation was decreased from 2.91 nmol/L (range,0.00-9.00 nmol/L) to 2.13 nmol/L (range,0.00-6.00 nmol/L),with no significant difference (F =-3.724,P ＞ 0.05).The remission rate of diabetes in group 3 was 14/18.There was no significant difference in the remission rate of diabetes of 3 groups (x2 =4.460,P ＞ 0.05).There were significant differences in the changing trends of fasting plasma glucose and BMI among the 3 groups (F =3.200,22.500,P ＜ 0.05).There were no significant differences in the changing trends of HbA1c and C-peptide among the 3 groups (F =0.720,1.640,P ＞ 0.05).Conclusion LRYGB surgery is feasible for the treatment of type 2 diabetes mellitus with effectively decreasing fasting glucose,and should be performed on patients with BMI ≥ 27.5 kg/m2 instead of patients with BMI ＜ 27.5 kg/m2 according to a correlation of blood glucose control and preoperative BMI.

Objective To prepare an active anti-tumor component, compound K (C-K), from saponins in leaves of Panax notoginseng (SLPN) using immobilized β-glucanase. Methods Two entrapments, alginate gel-1 (Alg 1) and alginate gel-2 (Alg 2), were evaluated for their ability to immobilize β-glucanase. The amount and purity of C-K obtained from the transformation process were analyzed by HPLC, and the immobilizing parameters were optimized. Results β-Glucanase can be immobilized and reused with either of the entrapment. However, using AIg 1 resulted in higher enzyme activity than Alg 2. The optimal concentration of the immobilized enzyme was 10%; The optimal crosslinking time was 4-6 h; and the optimal concentration of the crosslinking agent was 6%-7%. Conclusion Immobilized β-glucanase shows sustained enzyme activity, good ethanol tolerance, and was reusable for the preparation of C-K from SLPN.
