Objective To evaluate the feasibility and clinical significance of magnetic resonance cholangiopancreatography (MRCP) in the diagnosis of anatomic variants of the extrahepatic biliary tract. Methods The MRCP images of 535 patients who were admitted to The Second Affiliated Hospital of Suzhou University from March 2008 to March 2009 were retrospectively analyzed by two reviewers independently. The anatomic variants of the extrahepatic biliary tract were evaluated by studying the T2-weighted magnetic resonance images. Results The consistency between the two reviewers in the diagnosis of low choledochal joint, medial cystic duct insertion, aberrant hepatic duct, accessory hepatic duct and other anatomic variants was 98% , 99% , 89% , 90% and 100%, respectively (K = 0.86, 0.93, 0.81, 0.82, 1.00). The extrahepatic biliary system was clearly displayed by MRCP in 500 patients, and anatomic variants were observed in 240 patients, including low choledochal joint in 85, parallel cystic duct in 37, medial cystic duct insertion in 82, aberrant hepatic duct in nine, accessory hepatic duct in 10, choledochal cyst in three and high cystic duct in seven. A total of 259 patients underwent operation, and 168 patients had anatomic variants of the extrahepatic biliary tract. Conclusion MRCP imaging enables the accurate assessment of anatomic variants of the extrahepatic biliary system and avoids bile duct injury.

Objective To evaluate the correlation between low choledochal joint and common bile duct stones(CBDS)by magnetic resonance cholangiopancreatography(MRCP).Methods The clinical data of 129 patients without intrahepatic calculus after cholecystectomy receiving MRCP from March 2008 to August 2009 were retrospectively analyzed.MRCP images and T2WIs were analyzed independently by 2 doctors to classify anatomic variants of cystic duct and calculus.Results CBDS was found in 49 and low insertion of the cystic duct in 31 of the 129 patients(38% vs.24%).For the latter 31 patients, low insertion of the cystic duct with CBDS was found in 17.The analysis showed that low choledochal joint were associated with CBDS(x2 =4.921, P=0.027).Conclusion There is a certain correlation between low insertion of the cystic duct and CBDS.The low insertion of the cystic duct is one of the risk factors for calculus of the common bile duct.

Objectives To observe the effects of levetiracetam (LEV) on spatial learning and memory ability in epileptic rats and the expression of synaptophysin (SYN) and growth-associated protein 43 (GAP-43) in the hippocampus of rats with epi-lepsy induced by lithium pilocarpine (Li-pilo). Methods SD rats were randomly divided into normal control group (normal saline group), LEV group (treatment group), Li-pilo group (model group) and LEV control group (normal dose group). Twenty-four hours after the establishment of model, LEV (150 mg/kg per day) was given to rats in LEV group and LEV control group, and equivalent normal saline was given to rats in normal control group and Li-pilo group. At 7, 14 and 28 days after successful model building, the expression levels of the SYN and GAP-43mRNA in hippocampus of rats in each group were detected by RT-PCR. In the 4th week, the ability of learning and memory of rats in each group was evaluated by the Morris water maze. Results There was no significant difference in escape latency and the frequency of crossing platform between LEV control group and normal control group in Morris water maze test. Compared with normal control group, the rats in Li-pilo group had a longer latency to escape and reduced frequency of crossing platform (P<0.05). Compared with Li-pilo group, the rats in LEV group had shorter latency to escape and more frequency of crossing platform (P<0.05). There was no significant difference in the expressions of SYN and GAP-43mRNA in hippocampus of rats between LEV control group and normal control group. The expressions of SYN and GAP-43mRNA in Li-pilo group were lower than those of normal control group and LEV group (P<0.05). Conclusions Levetiracetam may improve learning and memory ability of rats with epilepsy through the regulation of SYN and GAP-43mRNA expressions in hippocampal tissue.

Objective To investigate the clinical effect of three kinds of dose of pulmonary surfactant (PS) in neonatal respiratory distress syndrome (NRDS), and to determine the optimal dose. Methods One hundred and seventy-four cases of NRDS were divided into A group (59 cases), B group (57 cases) and C group (58 cases) according random digits table. Based on the conventional treatment, children in A group were given large dose of poractant alfa injection 250 mg/kg, children in B group were given 200 mg/kg, and children in C group were given 100 mg/kg. After treatment for 1, 6, 12 and 24 h, the arterial oxygen saturation (SaO2), inspired oxygen concentration (FiO2), arterial oxygen tension (PaO2), oxygenation index (OI), arterial/alveolar oxygen tension ratio (a/APO 2), ventilator using and oxygen using time and the incidence of complication were compared. Results After treatment for 12,and 24 h, the levels of SaO 2 in A group and B group were significantly higher than those in C group: 0.936 ± 0.018, 0.935 ±0.019 vs. 0.857 ±0.027;0.941 ±0.017, 0.946 ±0.015 vs. 0.847 ±0.053, and there were significant differences (P<0.01). After treatment for 12 and 24 h, the levels of SaO 2 in A group and B group had no significant differences ( P>0.05). After treatment for 1, 6, 12, and 24 h, the levels of FiO 2 and OI in A group and B group were significantly lower than those in C group, and the levels of PaO 2 and a/APO2 in A group and B group were significantly higher than those in C group. There were significant differences (P<0.01). The levels of FiO2, OI, PaO2 and a/APO2 in A group and B group had no significant differences ( P>0.05). The ventilator using time in A, B and C group were (108.6±23.5) , (119.6±32.8), (156.3±27.3) h, and there were significant differences (P<0.05 or<0.01). The oxygen using time in A and B group had no significant difference ( P>0.05). The oxygen using time in C group was significantly longer than that in A and B group: (186.5 ± 52.8) h vs. (148.7 ±24.4), (154.6±28.2), P<0.01. The incidence of complication in A and B group had no significant difference ( P>0.05).The incidence of complication in C group was significantly higher than that in A and B group:29.31%(17/58) vs. 13.56%(8/59), 12.28%(7/57), P<0.05. Conclusions Poractant alfa injection 200 mg/kg is optimal dosage for poractant alfa injection in the treatment of NRDS, and it can effectively improve oxygenation and ventilation function, reduce the incidence of complication, shorten the course of disease and improve the prognosis and increase the cure rate. Excessive dose is waste, and little dose can not get effective treatment.

Objective To study the absorption mechanism of the antihypertensive peptide,Val-Leu-Pro-Pro-Val(VLPVP) in Caco-2 cell model. Method Caco-2 cell model was used in vitro to investigate the effects of time,pH,drug concentration,enhancers and inhibitors on the absorption of VLPVP. VLPVP concentration was measured by HPLC. Results The transport rate of VLPVP reached the maximal level at pH7.4,and was positively correlated to transport time and drug concentration. The peptide transporter inhibitors(Gly-Pro,arphamenine A) ,the endocytosis inhibitor(phenyl arsenoxide) didn’t influence the transport of VLPVP,while the paracellular transport enhancer(sodium deoxycholate) ,the inhibitor of multi-drug resistant protein(MK-571) and the energy inhibitor(sodium azide) enhanced it from apical to basolateral side significantly,but the latter two didn’t influence the transport from basolateral to apical side. Conclusion Paracellular diffusion was suggested to have been the main mechanism for the absorption of intact VLPVP and MRP2 had strong eflux effect on the transepithelial transport of VLPVP.

Objective:To observe the influence of emotional stress on the temporomandibular joint(TMJ) of SD rats. Methods:Standard animal model of emotional stress was created by emotion communication emergency box technique in 30 SD rats and foot-shocked in another 30. Control rats were 30 without treatment. The microstructure and ultrastructure of the disc surface, condylar surface and external pterygoid muscle were observed 1, 3 and 5 weeks after emotional stress treatment. Results:Obviously pathological changes were observed in the experimental animals, especially at 3 weeks, involving the fissures on the disc and condylar surface, the collagen fibers were disordered. Electron microscopy observation showed that condylar collagen was exposed. The mitochondria edema and vacuolar degeneration in the external pterygoid muscle were found.At 5 weeks, the condylar cartilage started to recover. Conclusion:Long term emotional stress may lead to pathological changes of the temporomandibular system. The changes can be partly recovered after a certain time of adaption of TMJ.
