The evaluation of outcomes of cancer therapy in clinic are largely based on volumetric and morphological evidences.These evidences,however,are very limited in assessing the early effects of therapy.Functional and molecular MR imaging allows co-registration of functional/molecular-based information with high-resolution anatomical detail within the same imaging modality,which makes it possible for assessing the early effects of tumor therapy.

Objective To summarize the experience of partial splenctomy in patients with traumatic spleen rupture.Methods Patients were assigned to spleen conservation group in which 59 patients underwent partial splenectomy,control group Ⅰ in which 60 patients underwent splenectomy and control group Ⅱ in which 60 patients underwent gastroinestinal operation. Immunologic function and filtration of red blood cell were detected in the three groups during the preoperation and the first month,the first year postoperation respectively.Results There was no significant difference between the spleen conservation group and the gastroenteric operation group.But IgM,NK-cell activity,T lymphocyte subpopulation and T lymphocyte transformation rate in the spleen conservation group were significantly higher then those in the splenectomy group (P

Objective To measure the length and diameter of the main bronchus using three-dimensional reconstruction from spi-ral chest computerized tomography scans in Chinese patients,and to evaluate the relationship between the BMI of patients and the length and diameter of main bronchi in order to provide the basis for pre-operative tracheal intubation.Methods 100 males and 100 females,who were scheduled to undergo a chest CT scan for physical examination,the diameter at the carina of the left and right main bronchus were measured.The length of the main bronchi extending from the carina to the line that is vertical to the bronchial wall at the starting point from the branches of the upper lobe was measured at the workstation.Results the length of the men’s right and left main bronchus was (1 9.7±5.2)mm and (50.3 ±4.7)mm.the length of the women’s right and left main bronchus was (18.2±4.1)mm and (46.3±4.5)mm,The length of the left main bronchus(LMB)was about 3-4 times greater than right main bronchus(RMB).the cross-section of the men’s left and right main bronchus was (175.3±29.6)mm2 and (209.4±32.7)mm2 ,the cross-section of the women’s left and right main bronchus was (120.5±24.8)mm2 and (144.4±33.7)mm2 .There was no signifi-cant relationship between the length and diameter of main bronchi and the BMI of patients.Conclusion The results showed that there was no direct relationship between the diameter and the length of main bronchi and the BMI of patients.BMI is not the criteri-on for choosing double-lumen tube (DLT)size.We proposed that three-dimensional reconstruction be used to measure the size of the main bronchi and determine the optimal size of the DLT in a clinical setting.

Objective To explore the isometric attachment site of the posterolateral structure in the femoral lateral condyle and introduce the method of knee posterolateral complex(PLC) reconstruction with the semitendinosus tendon. Methods Isometric reconstruction of the chronic PLC injury of knee joint in 18 cases, were performed with the semitendinosus tendon from February 2001 to February 2005. Of all patients, there were 12 males and 6 females, average age was 39 years old(range, 19-52 years old). All cases were chronic injuries, with duration of 1.5-14 months. 3 cases were simple PLC injury, 10 cases were PLC injury with posterior cruciate ligament(PCL) injury, 2 of which had undergone PCL reconstruction about 6.5 months. 3 cases combined with anterior cruciate ligament(ACL) injury, 2 cases combined with ACL and PCL injury. To put in the double semitendinosus tendon from the bony tunnel of anatomical insertion of the fibular collateral ligment in caput fibulae and put out from the bony tunnel of anatomical insertion of the popliterofibular ligment in the caput fibulae, then fix them respectively in the isometic bony tunnel of the femoral lateral condyle. The posterolateral stability of the knee was evaluated mainly through examination varus instability of knee and external rotation range of leg. Results It was relatively isometric from the femoral attachment site of the popliteal tendon to the anatomical insertion of the popliterofibular ligment in the caput fibulae. The better isometric attachment site was from the anatomical caput fibulae attachment site to 8-10 mm in front of the anatomical femoral attachment site of the lateral collateral ligament. The average follow-up period was 14 months(12-24 months). There was no varus knee instability in full extension. At 30? flexion, one-grade varus instability was found in 2. At 30? and 90? flexion, external rotation range increased by 6? in 3 cases, remained the same in 14 cases, and decreased in 1 case, all compared with the healthy side. Conclusion The method provided good stability for the knee and acquired satisfactory clinical results.

ObjectiveTo establish a rat model of nerve damage induced by intrathecal(IT) lidocaine.MethodsFifty-five adult male SD rats weighing 200-220 g were randomly divided into 5 groups (n =11 each):group normal control (group C); group dimethyl sulfoxide (DMSO)-the solvent(group D) and groups IT 5％,10％,15％ lidocaine (groups L5.10.15 ).IT catheter was successfully implanted without complication in groups D,L5,L1o,L15.DMSO,5％,10％ and 15％ lidocaine 20 μl were injected IT in groups D,L5,L10,L15 respectively.Motor dysfunction of hindlimb was assessed and scored (0 =normal,2 =complete block) and paw withdrawal threshold to mechanical stimulation (von Frey filaments) (MWT) and paw withdrawal latency to thermal nociceptive stimulus (TWL) were measured before (baseline) and at 1,2,3,4,5,7 d after IT administration in 8 animals in each group.Three animals in each group were sacrificed at 1 d after IT administration.The lumbar segment (L4-5) was removed for microscopic examination.ResultsThere was no significant difference in motor dysfunction score,MWT and TWL among groups C,D and L5.MWT was significantly increased and TWL prolonged at 1 and 2 d after IT administration in group L10,while in group L15 motor dysfunction score was significantly increased at 1,2 d after IT administration and MWT was significantly increased and TWL prolonged at 1,2,3 d after IT administration.There was significant histologic damage to spinal cord in groups L10 and L15.Conclusion Nerve damage can be induced by IT 10％ lidocaine.
