Objective To analyze retrospectively MRI features of ectopic pregnancy correlated with pathology.Methods Eleven patients with pathologically proved ectopic pregnancy were enrolled in this study:one with cornual pregnancy,six with interstitial pregnancy,two with tubal isthmus pregnancy,one with ampullary pregnancy,and one with primary abdominal pregnancy.Six under-went MRI plain scan,and five underwent MRI both plain scan and enhancement scan.We evaluated the location,the size,the signal intensity of the gestational sac (GS),vessels around the GS,dilatation tubal,hematosalpinx and hemoperitoneum.Changes of the thickness of the endometrium,functional ovarian cysts and ovarian corpus luteum were also evaluated.Results Among these eleven patients,GSs were detected in ten patients.The locations of the GSs on MRI were corresponding with the results of surgical explora-tion.GS was not detected in only one patient with tubal pregnancy,but hematosalpinx and pelvic hematocele could be seen in MRI. Conclusion MRI is an effective modality for evaluating GS and its adjacent organs.The imaging features of GS and other indirect signs can be helpful to the diagnosis and differential diagnosis of ectopic pregnancy on MRI.

BACKGROUND:With the continuous development and progress of medical model, the treatment and rehabilitation recovery from peripheral nerve defects needs higher requirements; therefore, stem cel culture-based nerve tissue engineering technology provides a new strategy for nerve defect repair. OBJECTIVE:To explore the feasibility of combining bone marrow mesenchymal stem cels and new nerve conduits to repair peripheral nerve defects. METHODS:Fifty New Zealand white rabbits, clean grade, were randomly divided into experimental group and control group, with 25 rabbits in each group. Animal models of peripheral nerve defects were made about 15 mm distant to the middle segment of the radius of the rabbit foreleg. At 1 week after modeling, bone marrow mesenchymal stem cels/new nerve conduit composite material was implanted into the defect in the experimental group; and in the control group, only bone marrow mesenchymal stem cels were transplantation. At 4 weeks after transplantation, a 5-mm nerve fiber was taken from the defect site, stained with hematoxylin-eosin and observed under scanning electron microscope. Density and diameter of regenerated nerve fibers were compared between the two groups. RESULTS AND CONCLUSION:Compared with the control group, the density of nerve fibers was significantly higher in the experimental group, but the diameter of nerve fibers was significantly lower (P < 0.05). There were more cels with good growth, large size and many processes on the surface of regenerated nerve tissues in the experimental group than the control group. Moreover, in the experimental group, interconnected cels were woven into a mesh and the axons were longer and thicker, both of which were the performance of typical neuron-like cels. Taken together, the bone marrow mesenchymal stem cels/new nerve conduit composite material can be used for peripheral nerve repair and present exact achievements.

Objective: To observe the anti-hypertensive effect of pomegranate polyphenols in spontaneously hypertensive rats ( SHR) and explore the underlying mechanism. Methods:Totally 40 male SHR rats at the age of 12 weeks were randomly divided into five groups:SHR control group, pomegranate polyphenols groups respectively at the dose of 120 mg·kg-1 , 240 mg·kg-1 and 480 mg ·kg-1 , and captopril group at the dose of 15 mg·kg-1 . The age-matched Wistar-Kyoto ( WKY) rats were randomly divided into two groups:WKY control group and pomegranate polyphenols group at the dose of 480 mg·kg-1 . All the rats were given corresponding drug or water by intragastric administration for four weeks. The systolic blood pressure ( SBP) and diastolic blood pressure ( DBP) were measured weekly. After the 4-week administration, the rats were fasted 12 hours and anaesthetized with 25% urethane solution. The blood samples were collected from abdominal aorta. The serum concentrations of angiotensin II ( Ang II) and endothelin ( ET) were de-termined by euzymelinked immunosorbent assay. The concentration of nitric oxide ( NO) in serum was determined by nitrate reduction test. Results:Pomegranate polyphenols could significantly lower the SBP and DBP, decrease the serum concentrations of Ang II and ET, and increase the serum concentration of NO(P<0.05 or P<0.01). In addition, pomegranate polyphenols had no effects on blood pressure and vasoactive substances in WKY rats. Conclusion: Pomegranate polyphenols has anti-hypertensive effect in SHR rats. The mechanism may be related to regulating the expression of vasoactive substances, such as Ang II, ET and NO.

Donation after cardiac death (DCD) means organ harvest and donation cannot be carried on until the requirement of death criteria using cardiopulmonary arrest is reached.Great success has been achieved since DCD was promoted widely in China.However,some problems were encountered during the implementation of DCD and there also exists many ethical controversies.The ethical principles of informed consent and no harm mentioned inDonation after Cardiac Death Work Instructions of China should be strictly adhered to,while justice,fairness and openness must be ensured in organ allocation.Appropriate compensation should be given to DCD donor and his family,and the utilization of DCD should be further improved.All of these ethical principles will help to promote the healthy development of organ donation and transplantation in China.
