The rat single-pass intestinal perfusion model was applied to study the effect of CYP3A and P-glycoprotein on the absorption of buagafuran in lumen of rats. Buagafuran concentrations in intestinal perfusate and blood in vena mesenterica collected at different time points after perfusion were determined by GC-MS. Permeability coefficient of buagafuran was calculated by the equation [P(lumen) = -(Q/2pirl)Ln(C(out)/C(in)) and P(blood) = (deltaM(B)/deltat)/(2pirl

Objective To investigate the CT features of mesenteric lymph nodes in patients with active Crohn’s disease.Methods The CT findings in 54 patients with active Crohn's disease proved by histology were analyzed,and the anatomic distribution,size, number,shape and enhancement ratio (ER)of the mesenteric lymph node were assessed.Results Mesenteric lymphadenopathy in 38 patients (70.4%)was found with a total number of 242,83.5%(202/242)of whom were located at the mesenteric root and 16.5%(40/242) at mesenteric edge.The size of the lymph nodes at the mesenteric root was larger than that at the mesenteric edge (8.57 mm±2.26 mm versus 5.38 mm±0.1 9 mm,the mean maximum short diameter),and 73.6% (1 78/242 )of the lymph nodes were oval in shape.The lymph nodes showed significant enhancement after contrast injection with an ER of 0.53 ±0.09.Conclusion Active CD often leads to mesenteric lymphadenopathy,which is more obvious at the mesenteric root.

Objective To produce a hybridoma secreting stable monoclonal antibodies against Aβ22-35 and to develop a detection method for the assay of Aβ. Methods Spleen cells from Balb/cmice immunized with Aβ22-35-KLH were fused with mouse myeloma cells SP2/0. The techniques of immunoprecipitation and western blotting plus ECL were used to investigate the levels of Aβ in the rat brain. Results Two strains of hybridomas (3A8 and 3B2) secreting stable monoclonal antibodies raised against Aβ22-35 were obtained. The subtypes of Aβ22-35 were IgG3. The levels of Aβ in young and older rat brain were 9.8±2.8 and 13.36±2.65 (pmol/12mg brain tissues, x±s), respectively. Conclusion The Aβ22-35 mAb obtained had high titres and specificity. The levels of Aβ in the older rat brain were significantly increased as compared with the young one (P<0.05).

Objective To discuss the femoral neck anteversion(FNA) of developmental dislocation of the hip(DDH) and guide operation with visual and digitalized picture in the dimensional(3D) CT.Methods Ninety children with unilateral DDH were selected,and they were analyzed using 3D CT.Children whose FNA exceed 45 degree received the subtrochanter osteotomy with images from different direction,FNA of hip was measured respectively before and after operation and was measured in normal and abnormal hips respectively,FNA of hip received respectively statistical treatment.Ninety patients (90 hips) were followed up ranging from 3 months to 2 years with the mean of 13 months.Results In the group younger than 18 months,the FNA whose in normal hips was(19.40?3.512)degree,the FNA while(68.45?12.272)degree in dysplasia hips respectively,the FNA measured after operation was (20.45?2.940) degree;in the group elder than 6 years,there were significantly statistical differences,the FNA in normal hips was(19.44?3.561)degree,in dysplasia hips respectively was(73.49?12.678)degree,while the FNA measured after operation was(18.28?1.931)degree.Clinical assessment was performed according to Mckay′s classification.The results showed that the overall excellent or good rate was 95.6%.Conclusions 3D CT method is a new accurate and convenient and reduplicative method for measuring FNA.It will be more helpful for related operations when 3D images are considered.

The levels of triglyceride(TG)and free fatty acid(FFA)in serum,liver,skeletal muscle,and pancreas of lipoprotein lipase gene knockout heterozygous(LPL+/-)mice and C57 mice were determined.Intraperitoneal glucose tolerance test(IPGTT)was performed to evaluate insulin sensitivity and β-cell function.The results showed that the Iipid content in 16 weeks LPL+/- group did not increase significantly.The TG and FFA contents in 28 weeks LPL+/- group were significantly higher than those in control and 16 weeks LPL+/-group(all P<0.05).In 50 weeks LPL+/- group,FFA levels in serum and pancreas,and TG content in pancreas increased significantly compared with other three groups(all P<0.05).The IPGTT result showed that the blood glucose levels increased from 15 to 120 min,not at 0 and 5 min.The blood glucose levels during 30-120 min increased significantly in 50 weeks LPL+/- group compared with other three groups(P<0.05).Fasting insulin(FINS),homoestasis assessment of insulin resistance(HOMA-IR)and pancreatic β cell function also increased gradually with age.FINS and HOMA-IR in 28 weeks LPL+/- group were higher than those in control and 16 weeks LPL+/- group.These results suggest that LPL is a key enzyme in lipid metabolism and plays a crucial role in the development of insulin resistance and diabetes.

Objective:To observe the clinical effect and adverse reaction of capecitabine as first-line monotherapy in elderly patients with stage Ⅱa breast cancer.Methods:From June 2002 to June 2005,71 elderly patients with stage Ⅱa breast cancer received chemotherapy(different scheme:capecitabine group and CEF group) after operation.The efficacies and adverse reactions were evaluated and compared between the two groups.Results:The 3-year and 5-year survival rates of patients in capecitabine group were 97.06% and 94.12%,respectively; the relapse rate was 5.88%; all were comparable to those of CEF group. One of the advantages of capecitabine was its oral administration. The adverse effect of capecitabine was mainly hand-foot syndrome,with an incidence of 82.35%,but was tolerable. The gastrointestinal reaction and bone marrow repression in capecitabine group were significantly lower than those in the CEF group(P

OBJECTIVETo investigate the mid-term outcome of operation for thoracolumbar tuberculosis. METHODS : Twenty-eight patiens with thoracolumbar tuberculosis underwent one stage anterior debridement,interbody fusion with bone graft and posterior pedicle screw internal fixation treatment from July 2006 to July 2011. There were 17 males and 11 females. Total 17 patients had nerve injuries ,including 6 cases of grade B, 5 cases of grade C, 6 cases of grade D according to Frankel classification. The poisoning symptoms of tuberculosis and recovery of spinal function were observed. The bone fusion and recovery of [umbar function were evaluated.
RESULTSAll the patients were followed up ,and the duration ranged from 39 to 85 months (mean 57 months). The clinical symptoms were controlled gradually, and the thoracolumbar back pain was alleviated after operation. Among the 17 patients with complications of nerve injuries, 3 patients were improved from preoperative grade B to postoperative grade D, 3 patients were improved from preoperative grade B to postopertive E, 5 patients with preoperative grade C and 6 patients with preoperative D were almostly recovered to normal after operation. According to JOA scoring system for curative effect evaluation, the excellent and good rate at the 3rd month, the 1st year, the 3rd year and the 5th year after operation were 67.86% ,82.14% ,85.71% ,89.29% and 91.30% respectively. The results at the 6th month and the 1st year had no statistical differences compared to the results at the 3rd month (P > 0.05); but the results at the 3rd year and the 5th year were better than that at 3 months after operation (P < 0.05); and the results between 3 yesrs and 5 years after operation had no statistical differences (P < O.05). The degeneration of adjacent segments were evaluated according to the California University (Universith of California at Los Angeles , UCLA) score. The degeneration rate was 53.57% (15/28) at the 3rd year after surgery, which was better than that before surgery. Twenty-three patients were followed up for 5 years ,and the degeneration rate was 86.96% (20/23) ,which was better than those of before surgery and 3 years after surgery.
CONCLUSIONThe surgical treatment for thoracolumbar spinal tuberculosis can achieve the thorough debridement, reconstruction of spinal stability, recovery of lumbar function and promote the functional recovery of the spinal cord, which is an effective method of treatment. However, the mid term follow-up showed that more severe degenerative changes were found in the postoperative adjacent segment.
