A gas chromatographic method was established for the analysis of fatty acid composition of oils. After methlation of the samples, the retention time of the fatty acid esters in the glass capillary coated with crosslin-ked methyl silicone was closely related to the number of carbon atoms.The reproducibity of this method was satisfactory. The relative standard deviation was 0.4-1.5%. Six kinds of vegetable oils were analyzed by this method, and the results were consistent with those reported by Canadian Cereal Association. For analysis of the free fatty acid composition of becte-ria, the results were comparable with those obtained from thin layer chroma-tography and chemical analysis.

Objective To explore significance and impact of hypoxia inducible factor 1α,metastasis associated with colon cancer 1 and transcription factor FOXO4 in gastric carcinoma and clinical pathological characteristics and prognosis .Methods 110 samples diagnosed as gastric carcinoma and 46 samples diagnosed as pericarcinomatous tissue which was 5 cm far away from cancer were collected in first affiliated hospital of Anhui medical university from December 2006 to May 2008 .Immunohistochemical stai-ning was performed in these samples to detect the expressions of HIF-1α,MACC1 and FOXO4 .And the correlation between devel-opment of gastric carcinoma and expressions of HIF-1α,MACC1 and FOXO4 was analyzed with the help of patients′messages .Ka-plan-Meier method and Cox regression were used to analyze patients′5 years survival rate and the factors .Results The expression levels of HIF-1α(P<0 .001) and MACC1(P<0 .001) in gastric carcinoma tissues were significantly higher than pericarcinomatous tissues ,however the expression levels of FOXO4(P<0 .001) was significantly decreased in gastric carcinoma tissues .Statistical a-nalysis revealed that the expressions of HIF-1αand MACC1 were apparently increased with the lower degree of cell differentiation , the greater degree of tumor infiltration ,accompanied with lymph node metastasis and higher TNM scores ,but lowered the expres-sion of FOXO4 factor .There were significant correlations between expressions of the three factors in gastric carcinoma .The expres-sions of HIF-1α,MACC1 and FOXO4 had an apparent influence on the patients′5 years survival rate .And they were independent factors on the prognosis of gastric carcinoma .Conclusion HIF-1α,M ACC1and FOXO4 are abnormal expression in gastric cancer tissue ,and the clinical pathological features of gastric cancer and the prognosis of patients with gastric cancer are closely related .

Objective To evaluate the application value of hip joint traction device in treating serious developmental dysplasia of the hip. Methods From April 2006 to October 2008, 6 cases Crowe Ⅳ hip dysplasia and 1 case dysplasia of acetabulum in coxa vara underwent arthroplasty. There were 2 males and 5 females with an average age of 30 years (range, 12-45). All patients were admitted to the hospital for the distraction, which was 1.0-2.0 cm on the first day and 1 mm/d thereafter, until slowly pulling femur head to the real acetabulum. Changing to the skin distraction with 3 kg, arthroplasty was performed after pin sites healing. Results Seven femur heads of 5 cases and two greater trochanters of 1 case were pulled into the real acetabulum, average distraction length was 4.45 cm, and average time was 43 d, no nerve injury and infection of pin sites. Soft tissue release and femur shortening were not required in arthroplasty. One case accelerated pulling speed to 1.25 mm/d when left femur head was distracted to 6.0 cm, so that the partial left deep peroneal nerve injury happened after 12 h. Ending distraction, bilateral THA was undergone by stages and femur shortening 3 cm in operation, nerve injury restored after half year. All patients were followed up for average 2.5 years (range, 1.5-3.0). In all patients, two limb lengths were equal, middle gluteal muscle myodynamia improved about 1-2 grades. The mean Harris hip score improved from 56.2 to 92.2 one year after operation. Conclusion The hip joint traction device could pulled femoral head to the real acetabulum rotating center, as a result, femur shortening and soft tissue release were not required while performing arthroplasty, and through which wound and operative time were decreased, middle gluteal muscle function was improved. However, we should strictly pulled the femur head at 1 mm/d to avoid nerve injury.

Objective To compare the anesthetic effects of remifentanil and fentanyl in elderly patient undergoing transurethral electro-vaporization of the prostate.Methods Eighty cases of the elderly patients (age ≥60 years) with transurethral resection of the prostate operation in the hospital were randomly divided into remifentanil group(R group,n =40) and fentanyl group (F group,n =40).Patients in R group and F group were administrated remifentanil and fentanyl respectively for induction and maintenance of anesthesia.The following indices were recorded including the changes of emodynamics (lood pressure,heart rate) in before-and after-anesthesia,postoperative recovery (spontaneous breathing recovery time,open the recovery time,extubation time) and the adverse reaction within 24 hours after operation (awareness during operation,nausea,vomiting).Results Blood pressures,heart rate of after-anesthesia in R group were lower than that in before-anesthesia and F group,the difference were significant(Blood pressures:F within group =58.306,P within group =0.000,F interactive group =142.450,p interactive group =0.000,F between group =7.417,P between group =0.010;heart rate:F within group =41.512,P within group =0.000,F interactive group =269.103,P interactive group =0.000,F between grouP =39.703,P between group =0.000).Spontaneous breathing recovery time,opening eye time and extubation time in group R were significantly shorter than that of F group (Spontaneous breathing recovery time:(7.5 ± 1.3) min vs.(10.7 ± 3.1) min,t =3.011 ; Opening eye time:(13.5 ± 3.2) min vs.(18.3 ± 5.2) min,t =2.611 ; Extubation time:(24.4 ± 5.5) min vs.(29.2 ± 7.1) min,t =2.696 ; all P ＜ 0.05).No significant differences were found in R and F group in terms of intraoperative awareness postoperative nausea,vomiting (P ＞ 0.05).Conclusion Remifentanil used in elderly patients with transurethral electro-vaporization of the prostate was safer and more effective than fentanyl.Meanwhile postoperative recovery in Remifentanil patient was more rapidly.Therefore Remifentanil was ideal drug during the process clinical anesthesia.
