Objective To investigate the effect of different concentrations of heparin in the cold preservation solution on blood coagulation after reperfusion during orthotopic liver transplantation ( OLT) . Methods Forty ASA Ⅱ or Ⅲ patients with end-stage liver disease (31 males, 9 females) weighing 51-82 kg undergoing OLT were randomly divided into 3 groups according to the concentrations of heparin in the liver preservation solution: group Ⅰ 2 000 U?L-1( n = 14); group Ⅱ 8000 U?L-1(n= 12) and group Ⅲ 20 000 U?L-1(n = 12) .Anesthesia was induced with propofol, fentanyl and rocuronium and maintained with isoflurane inhalation and intermittent i.v. boluses of fentanyl. Body temperature was maintained at 35.5-37.5℃ and Hct at 22%-35% . Blood samples were taken from central vein at 15 min before reperfusion (T0,baseline) and 5, 30, 60, 120 and 180 min of reperfusion (T1-5) for determination of ACT, CR and platelet function (PF) using Sonoclot platelet function and coagulation analyzer (U.S.A.). Blood concentration of heparin was determined in 3-4 patients in each group at T0-5 ( HPLC) . Results The 3 groups were comparable with respect to age, body weight, ASA physical status and Child classification. The glass ball activated coagulation time (gbACT) was significantly prolonged at T1-4 in group Ⅲ and at T1,2 in group Ⅱ as compared to the baseline values at T0 ( P

The connotations of "du-fu" and "Sanli" in "Sanli acupoint for du-fu diseases" are discussed in this paper, which can provide theoretical foundation for the clinical application of "Sanli acupoint for du-fu diseases". Based on ancient literature combined with related theories in the Huangdi Neijing (Yellow Emperor's Canon of Internal Classic), a deep discussion is performed through the relationship between Zusanli (ST 36) and stomach, indication and mechanism of Zusanli (ST 36) on du-fu diseases and comparison between Zusanli (ST 36) and Shousanli (LI 10). It is believed that "du" should be pronounced as "dŭ", meaning stomach, and it indicates that Zusanli (ST 36) is closely related to stomach and spleen when it is used for du-fu diseases; "fu" means abdomen area, including liver-gallbladder, spleen, stomach-intestine, kidney, uterus, triple energizer; "sanli' means exclusively the acupoint of Zusanli (ST 36).

Objective To summarize the important HR-MRI manifestations of orbital disease in extraconal compartment.Methods Forty-four patients with extraconal orbital disease identified pathologically were analysed retrospectively. MRI of the orbit at 1.5 Tesla was performed with surface coil, thin slice, suitable bandwidth, small field of view (FOV) and large matrix. The analyzed criteria of imaging appearance were: location, shape,size, margins, extent, adjacent structures, and signal intensity.Results Lymphoma, hemangioma, rhabdomyosarcoma, metastasis, pseudotumor, and phlegmon accounted for 70% of all extraconal orbital diseases. Three cases of haemangioma had round shape and clear margin; most lymphoma had irregular shape, unclear margin and big volume; while most rhabdomyosarcoma and metastasis had round shape and unclear margin. The effect of space-occupying of lymphoma was not obvious. One case of lymphangioma had high signal intensity on both T 1- and T 2-weighted images without enhancement. Melanomametastasis appeared hyperintense on T 1- weighted and hypointense on T 2-weighted images. The contrast-enhancement of haemangioma was much more prominent than others. There were characteristic of rhabdomyosarcoma, metastasis, pseudotumor, and phlegmon about their age,clinical history and examination. Conclusion Location criteria, morphological changes, MRI signal intensity, clinical history and the effect of space-occupying are very useful in the differential diagnosis of the orbital disease.

Objective To investigate the clinical efficacy and indication of surgical treatment of L5S1 tuberculosis us?ing a medial edge of rectus abdominal muscle and retroperitoneal approach. Methods From Jan. 2010 to Nov. 2014, totally 18 cases of L5S1 tuberculosis were surgically cured by debridement, fusion and internal fixation via a medial edge of rectus ab?dominal muscle and retroperitoneal approach. There were 10 males and 8 females, with an average age of 35.6±10.1 years (21 to 55). The mean course of disease was 5.3±2.2 months. The primary destruction lesions were located at L5S1, and one patient of whom L4 was also involved, three cases S2 involved, and one S3 involved. Abscess pre sacrum was noticed in all cases. Six patients were combined with abscess in vertebral canal. Neural deficiency was detected in 3 patients, all grading as Frankel D. Dubousset's lumbosacral angle was 104°-126°, mean 114.6°±6.0°. Formal anti?tuberculosis medicine treatment was given for at least 2-3 weeks. All patients were treated using a medial edge of rectus abdominal muscle and retroperitoneal approach. Af?ter debridement, a tri?cortical iliac bone was used for structural inter?vertebrae fusion. The iliac bone was fixed to the sacrum by one cortical screw. Operation time, volume of blood loss, and surgery complications, including wound infection, looseness and shift of internal fixation, sinus occurrence, vascular injury, retrograde ejaculation in male patients were evaluated. The X?ray and 3D CT of lumbosacral spine, together with ESR and CRP were used to evaluate the control of tuberculosis during fol?low?up. The Dubousset's lumbosacral angle, visual analogue score, and the Frankel grade were compared between preoperative and postoperative. The bone graft fusion were also observed. Results The operation time was 147±16 min in average. The mean blood lose was 275 ± 77 ml. No vascular or neurological injury was noticed. There was also no retrograde ejaculation happened in this group. All patients were followed up from 18 to 28 months. Dubousset's lumbosacral angle was 122.4°±3.8° post?operatively and 121.4°±3.7° at the final follow?up. There was a significant difference between the lumbosacral angles pre and post operation, whereas no statistical difference between the post operation and the final follow?up. Bone fusion was noticed in all cases. All pa? tients have intact neurological function at the final follow?up. No screw breakage or graft bone migration occurred. VAS was 5.6± 1.09 pre?operation and 0.83±0.71 at the 3rd month's follow?up, and there was a significant difference between them. Conclusion Surgical treatment of L5S1 tuberculosis by debridement, fusion and internal fixation via a medial edge of rectus abdominal muscle and retroperitoneal approach is an effective method in terms of minimal trauma, low rate of modality, good ability in restore and maintenance of lumbosacral junction alignment and high fusion rate.

To lay a foundation for the type selection of the ambulance helicopter. The type selection was explored from the aspects of platform selection, rescue environment and service requirements, analyzing the rescue in the helicopter and the tendency of the ambulance helicopter in foreign countries and China. The types of the am-bulance helicopter were determined as the specific and modified ambulances, with the considerations such as operation environment, flight performance, cabin structure, onboard equipment, cabin configuration, fixation device and protection. Specific ambulance helicopter is supposed to be based on small- or mediate-sized platform, while the modi-fied ambulance helicopter is supposed to be based on large or heavy platform.

Objective To investigate HR-MR imaging characteristics of non-Hodgkin lymphomas (NHL) of the orbits in extraconal compartment. Methods The HR-MR images of 16 patients with NHL of the orbits identified pathologically were retrospectively analyzed. MRI of the orbit at a 1.5 T scanner was performed with 4-cm surface coil, thin slice, suitable bandwidth, small FOV, and large matrix. T1-weighted (before and after i.v. bolus injection of contrast medium) and fast spin-echo T2-weighted sequences were acquired in all patients. All cases were performed with fat suppression techniques. The analyzed criteria of imaging appearance included location, number, size, shape, margins, extension, adjacent structures, and signal intensity of the lesions. Results The lesions in 13 of 16 cases located in anterior part of extraconal compartment, posterior to the orbital septum, and with irregular cast shape. The other 3 patients showed diffuse lesions with infiltration in extraconal compartment and with irregular shape. Eleven lesions had the large volume above 3.0 ml, 4 lesions with medium volume ranging from 1.0 to 3.0 ml, and only one with small volume less than 1.0 ml. 13 cases had a poor-defined margin with infiltration of extraocular muscles, but without mechanical shift of the muscles. 7 patients had infiltration of eyeball, but only 3 cases with exophthalmos. Destruction of orbital bone was evident in 2 cases with diffuse lesions but never in isolated orbital lymphoma. On the T_1-weighted images, the signal intensity of the lymphoma was isointense compared with that of the muscle in all patients. The T_2-weighted fast SE images showed a hyperintense signal in 13 cases and intermediate in 3 cases. All lesions enhanced after intravenous Gd-DTPA administration, 15 cases with homogeneous enhancement, and 10 cases with reliably visible enhancement in the T_1-weighted fat-suppressed sequences. Conclusion Most NHL of the orbits in extraconal compartment have the characteristic findings on HR-MR imaging, including anterior part of extraconal compartment location, posterior to the orbital septum, irregular cast shape, large volume, poor-defined margin with infiltration but without mechanical shift of extraocular muscles, uniform signal characteristics and marked enhancement after injection of contrast medium, and without bony destruction in isolated orbital lymphoma. The understanding of HR-MRI features of orbital NHL in extraconal compartment is very useful for making the differential diagnosis with other orbital diseases.
