Objective To explore the relationships between cholangiocarcinoma and clonorochiasis or hepatolithiasis,and to compare their MRI features.Methods The MRI features in 37 patients with cholangiocarcinoma confirmed by surgery and pathology were retrospectively analyzed,including clonorchiasis with cholangiocarcinoma in 21 (group A)and hepatolithiasis with this tumor in 16 (group B).The analyzed parameters included the location,size,shape,signal intensity and enhancement pattern of the tumor and the characteristics of bile duct dilatation.Results In group A,the tumors were located in the right lobe in 12 (57.2%),left lobe in 4 (19%),and porta hepatic in 5 (23.8%).In group B,those were located in the right lobe in 3 (18.7%),left lobe in 9 (56.3%),and porta hepatic in 4 (25%).There was a significant difference in the left/right lobe between two groups (P<0.05),however,no significant difference was found in porta hepatic (P>0.05).The MRI showed the tumors with low signal on T1 WI and high or heterogeneous signal on T2 WI,and with peripheral enhancement in early stage and delayed centric enhancement in 34 patients.Diffuse saccular dilatations of terminal intrahepatic bile ducts were showed in 1 6 (7 6 .2%)in group A and 1 (6 .2%)in group B,meanwhile the dilatations of bile ducts within tumors were showed in 2 (9.5%)in group A and 13 (81.3%)in group B,exhibiting significant differences between the two groups (P<0.05).Conclusion Clonorochiasis and hepatolithiasis are related with the cholangiocarcinoma.No differences in MRI features of cholangiocarcinoma are found between the two groups,however significant differences in location and the features of bile duct dilatation are observed.

BACKGROUND: The problem of the high rate of acute restenosis at an early and advanced stage has been a hot spot, while the stent with paclitaxel (poly-L-lactide, PLLA/polyglycolic acid, PGA) degradable material will resolve it. OBJECTIVE: To seek an ideal biologic degradable material used in biologic degradable stent. DESIGN, TIME AND SETTING: The comparative cytological study was performed at the Laboratory of Toxicology, Institute of Public Health, Jilin University (Key Laboratory of Radiobiology of Ministry of Public Health of China, Key Laboratory of Toxicology of Jilin Province) from July 2003 to July 2005. MATERIALS: Paclitaxel degradable material (PLLA/PGA) (PLLA:PGA= 9: l ) were offered by Changchun Applied Chemistry Institute of Chinese Academy of Science). Human umbilical arterial smooth muscle cells (SMCs) were purchased from Boster, Wuhan, China. METHODS: The sixth passage of SMCs were digested by 0.25% Trypsin under ambient temperature for 3 minutes, incubated in 10 mL 10% ox serum BMEM, and made into SMC suspension. The materials kept in hypothermal disinfectant Co60 were heated to 37 ℃ by waterbath after surface treatment, and then placed in a 6-well culture plate. SMC suspension was added into the middle of the materials. The density of cells was about 5×106/cm2. Cell suspension diffused around the materials gradually. At last, 10% ox serum BMEM culture solution was added into it, and cultivated in a 5% CO2 incubator at 37 ℃. The growth of cells in and surrounding the materials was observed by inverted microscope everyday. MAIN OUCOME MEASURES: The materials were obtained after culture for 3, 6, 12, 19, 26, 34 days and vacuum dehydration, and were weighed. The weight loss of materials was compared before and after culture. The average degradable rate of materials was calculated.RESULTS: Degradable material had no influence on the development of SMCs. The average degradation rate ex vivo was 0.45% per day. CONCLUSION: PLLA/PGA with good cellular compatibility could be applied to intravascular stents.

Objective To systematically review the effect of team-based learning (TBL) versus the traditional lecture-based learning (LBL) teaching model on basic medical courses in undergraduate medical education. Methods The CNKI, VIP and Wanfang medical databases were electronically searched to retrieve randomized controlled trial studies on TBL applied in undergraduate basic medi-cal courses up to June 2014. In these studies TBL teaching model was used in experiment group with LBL teaching model as control group and course grades were adopted to evaluate the effect of learn-ing. Literature screening, data extraction, and quality assessment were performed in strict accordance with the inclusion and exclusion criteria, and then data were analyzed using RevMan 5.3 software. Results This Meta-analysis examined 12 studies, all of them with low quality at C level. Meta analysis shows that the score of the course of TBL teaching is better than the traditional LBL teaching, and the difference is statistically significant [weighed mean difference (WMD): 9.33, 95%CI (5.67, 13.00), P=0.000]. Conclusion Compared with the LBL teaching, the application of TBL teaching in medical undergraduate basic medical courses has the promotion effect, but need more rigorously randomized controlled trials to verify.

32 cases of children small cerebral abscess di-agnosed with CT scaning are reported. The maxi-mum diameter of the enhancement area was 2. 2cm. 29 cases did not give a history of infection. In30 cases, Epileptic seizures were usually the Initialand main symptoms, but local neurological signswere usually absent. All of the cases were treatedby antibiotic therapy. The duration of the therapyin most childhood patients was 2～3 months exceptthree who were over 3 months.

Objective To observe the difference of FKBP-12 expression level between in Alzheimer's disease model mice's brains and in control mice's brains.Methods Taking the Senescence Accelerated Mouse imported from Japan(SAM-P/8)as the Alzheimer's disease model mouse,and SAM-R/1 mouse as control,observe the distribution difference of FKBP-12 between in Alzheimer's disease model mice's brains and in control mice's brains both in mRNA level and in protein level with the methods of RT-PCR and immunohistochemistry staining.The mice were divided into four groups of 4,6,8,10 months old.Results There was no distribution difference of FKBP-12 between in Alzheimer's disease model mice's brains and in control mice's brains both in mRNA level and in protein level.Conclusion FKBP-12 probably has no relativity with the accelerated aging process of the Alzheimer's disease model mice imported from Japan.

Fifty adult lower limbs were studied macromicroscopically to reveal the extrinsic blood vessels of the menisci of the knee joint. It was found that the menisci were supplied from 2 sources, the genicular branches (except the superior lateral genicular branch) of the popliteal artery, and the descending branch of the descending genicular artery. A pair of additional genicular branches with independent stems from the popliteal artery, named as the posterior medial and the posterior lateral genicular arteries by the authors, constantly supplied the posterior part of both the menisci. The arterial branches formed a circular anastomotic arch around the menisci with small branches springing from the arch and getting into the menisci. The arterial arch communicated with the femoral and the popliteal arteries and became an important stem of a reentry channol in cases of popliteal artery occlusion.
