OBJECTIVE:To establish an RP-HPLC method for determination of the contents of oleinic acid and linolic acid in Brucea javanica oil. METHODS:The derivative fatty acid was obtained from extracting and separating process using ?-bromo-acetophenone as derivative reagent,K2CO3 as base and N,N-dimethylformamide (DMF) as solvent. The sample was separated on Shim-pack VP-ODS column(150 mm?4.6 mm,5 ?m); the detection wavelength was set at 242 nm. The mobile phase consisted of methanol-acetonitrile-water(30∶20∶50). RESULTS:The linear ranges of oleinic acid and linolic acid were 0.025～1.0 mg?mL-1(r=0.999 6) and 0.1 ～ 0.8 mg?mL-1(r=0.999 0),respectively. The average recoveries were 98.54% and 98.50%,respectively,and their RSD were 1.81% and 1.90%,respectively (n=6 each). CONCLUSION:The method is accurate and specific,and it is applicable for the quality control of B.javanica oil.

Objective To study the role of extra-anatomic arterial bypass grafting in the management of aorta-iliac occlusive disease. Methods Forty-one cases of aorta-iliac occlusive disease managed by extra-anatomic arterial bypass grafting were retrospectively analyzed. Clinical features included claudicafion 11, resting pain 12 and ulcer/gangrene 18 patients. Axillofemoral bypass was performed in 15 cases with aortic and bilateral iliac artery occlusion, femorofemoral bypass in 18 cases with unilateral iliac occlusion and femoro-cnntralateral popliteal bypass in 8 cases with iliac and ipsilateral femoral artery occlusion. Results Postoperatively, clinical features were reheved in 40 cases (97.6%). Ankle brachial index increased significandy from 0.41 ± 0.15 to 0.89 ± 0.21 perioperatively (P < 0.05 ).Thirty-five cases were followed up for 1 year to 5 years. The overall graft patency rates in this series were 93%, 86% and 80% in 1, 3 and 5 years, respectively. Conclusion Extra-anatomic arterial bypass has merits as less invasive and rapid postoperative recovery, and this is one of the effective methods for the treatment of aorta-iliac occlusive disease.

Objective To investigate the clinical efficacy of percutaneous kyphoplasty(PKP) in treatment of elderly osteoporotic vertebral compression fractures(OVCF).Methods 122 elderly OVCF patients from Oct.2009 to Oct.2013 in Lihuili Hospital of Ningbo Medical Center were selected,and were randomly divided into group A,and group B.There were 61 cases in each group.Group A received percutaneous kyphoplasty(PKP),and group B were treated with percutaneous vertebroplasty(PVP).The two groups were observed in terms of pain,activity,vertebral compression rate and Cobb angles after treatment.The two groups were followed up at least for 3 months.The postoperative side effects were recorded and analyzed.Results After the treatment,the two groups significantly improved in VAS score and activity(P ＜ 0.05),but no significant difference was found between the two groups (P ＞ 0.05).After the treatment,vertebral compression rate and Cobb angle got better than before in the two groups,but group A recovered more obviously than group B,and the difference had statistical significance (P ＜ 0.05).The postoperative recurrence rate was 18.03 ％ (11/61) in the observation group and 9.84 ％ (6/61) in the control group,and the difference had statistical significance (P ＜ 0.05).Conclusion PKP and PVP can significantly relieve pain,but PKP had better effect than PVP in vertebral body and spinal kyphosis improvement,which is worth of clinical application.

Objective To understand demonstration methods and ultrasonographic features of left and right atrial appendages in normal fetuses.Methods 200 consecutive normal fetuses during gestation age 19-28 weeks from November 2011 through April 2012 entered the study.Ultrasonographic features and the demonstrated rates of atrial appendages at different incidence angle of ultrasonography and different gestational weeks were recorded and calculated,respectively.Results Atrial appendages of normal fetuses can be demonstrated on atrial appendages plane,which was little lower the view of parasternal great artery short axis.The display rate of left,right and left-right atrial appendages was 92％,68％,65.5％,respectively.When ultrasound beam entranced into chest from the right side,the display rate of left-right atrial appendages was highest(94.3％).The best time to observe atrial appendages was 22 to 24 week of pregnancy.The majority of left atrial appendages were fingerlike hook shapes,with narrower bases and longer bodys,and the endocardial surfaces were relatively smooth.Sometimes with incisures on external edges.Whereas the majority of right atrial appendages were obtuse-angled triangle shapes,with broad bases and shallower bodys.On endocardial surface the pectinate muscles were often seen,which looked like serrated echoes,sometimes prominent taenia sagittalis were noted in right atrial appendages.Conclusions Atrial appendages of normal fetuses can be demonstrated using two-dimensional ultrasonography on atrial appendages plane.The demonstrated rates of atrial appendages were different according to different incidence angle of ultrasonography and gestational weeks.There were some differences in ultrasonographic features between left and right atrial appendages,which is very helpful in determinating atrial situs.

Objective To observe the outcomes of fast track surgery program applied in thoracoscopic/laparoscopic esophagectomy.Methods From March 2010 to December 2012,99 esophagus cancer patients were randomly allocated to receive thoracoscopic/laparoscopic esophagectomy[minimally invasive esophagectomy (MIE) group,50 cases] and open esophagectomy [open esophagectomy (OE) group,49 cases].Same fast track surgery program was applied in both groups.Perioperative data of all patients were collected and analysized.Results The baseline of both groups was similar.Compared with OE group,MIE group got more abdominal lymph nodes resection,13(6-40) vs.4(0-20),P ＜0.05.In both groups,the level of the total albumin,hemoglobin and total cholesterol in the 8th postoperative day was higher than that of the 1 st postoperative day,P ＜0.05.Statistical difference was observed in the 48 h patient controlled analgesia usage,24 h and 48h visual analogue scales score of motion and less motion,postoperative creatine kinase level,the white cell count and C-reaction protein level in the 8th postoperative day,of which the MIE group got better results,P ＜ 0.05.Patients in MIE group took less time to begin oral nutrition (6 days vs.9 days P ＜ 0.05),besides,the parenteral nutrition duration [(7.9 ± 2.4) days vs.(8.6 ± 2.9)days,P ＜ 0.05] and postoperative hospital stay [(12.5 ± 3.1) days vs.(17.1 ± 6.3) days,P ＜ 0.05] were also shorter,P ＜0.05.Conclusion Fast track surgery program is safe and feasible for patients receiving esophagectomy.MIE combined with fast track surgery program can promote early rehabilitation by easing pain,reducing inflammatory response,improving nutrition state,lowering postoperative morbidity,shortening hospital stays,and as a result,have more obviously advantages.

Objective To investigate the safe region for screw fixation in atlas lateral mass by ra- diologic measurements to conduct the operative procedure.Methods The dimensions of the pedicles were determined in 30 patients with normal atlas by CT scan and three dimensional reconstruction images of the upper cervical spine.The space available for the screw(SAS)was defined as the perpendicular distance between two lines tangential to the spinal canal and the transverse foramen,respectively.SAS was evaluated at 0?(SAS1)and 10?(SAS2)insertion angles.The location of screws in 13 cases of opera- tion were observed by CT scan images measurements of the cervical spine.Results SASI at 0?inser- tion angle was(7.81?1.28)mm and SAS2 at 10?insertion angle was(9.69?1.23)mm,with statisti- cal difference(P＜0.01).For SAS1,the distance from the midline of pedicle to the midline of posterior arch and the distance from the center of C2 inferior articular process to the midline of posterior arch showed insignificant statistical difference.However,the entry point at the posterior arch of the midline of SAS2 was located at 2.0 mm lateral to the midline of ASAI.Twenty-six pedicle screws in 13 cases were inserted correctly,without cortex breakage,or nerve and vessel injury.Conclusions There is a safe region for screw fixation in atlas lateral mass.Wider space available for the screw can be acquired when transverse angle is 10?.It is necessary to confirm the safe region by using axial CT of atlas before screw fixation.
