Objective To evaluate the effect and safety of ultrasound-guided percutaneous thrombin injection for the treatment of postcatheterization femoral arterial pseudoaneurysm.Methods Seventy-eight patients with femoral anterial pseudoaneurysm were included in this study.Pseudoaneurysms were treated by bedside compression in 50 of these 78 patients(group A),and by thrombin injection in 28 patients(group B).All patients were diagnosed by GE LOGIQ 9 Color Doppler Ultrasound.Ultrasound guided thrombin injection for femoral arterial pseudoaneurysme were carried out in patients in group B.Results Closure of the pseudoaneurysm was successfully in 82 percent(41/50) of the patients in group A.Six patients had vagus reflex,4 patients could not tolerate repeating compression and 5 patients were not effectively cured by compression and needed to receive remedial ultrasound-guided percutaneous thrombin injection.Closure of the pssudoareurysm by percutaneous thrombin injection was successful in all patients in group B.Successful immediate closure were noted in 25 patients and 2 patients needed second thrombin injection.One patient had vasovagal syncope and 12 patients had mild fever.No distal embolization,infection,hemorrhage or allergic reaction occurred.Conclusion Compared to compression therapy for treatment of femoral arterial pseudoaneurysme,ultrasound-guided percutaneous thrombin injection is a simple,safe and effective treatment alternative.

Objective　To study the viability and histological change of encapsulated rat hepatocytes after being transplanted into abdominal cavity of rat. Methods　The two-step collagenase perfusing method was used to separate hepatocytes from Wistar rat liver. The separated hepatocytes were purified with Percoll density gradient centrifugation and encapsulated by the alginate-barium method. Then the purified hepatocytes were transplanted into abdominal cavity of SD rats (group 1) and the encapsulated hepatocytes were transplanted into abdominal cavity of SD rats (group 2) and Wistar rats (group 3). At different time points post-transplantation, trypan blue stain exclusion was used to determine the viability of recovered hepatocytes. The histological changes of transplanted microencapsulated hepatocytes was examined using HE stain. Results　Twenty-four h after transplantation, the viability of hepatocytes between group 1 and group 2 showed significant difference (P<0.01), but there was no significant difference between group 2 and group 3 (P>0.05). At day 4 and day 7 after transplantation, the viability of hepatocytes showed significant difference between group 1 and group 2, and group 2 and group 3 (P<0.01). At day 14 after transplantation, no significant difference was found in the viability of hepatocytes between group 2 and group 3 (P>0.05). From day 4 post-transplantation, fibrosis overgrowth was found around some microencapsules, and it was more obvious in group 2 than in group 3. Conclusions　 Microencapsulation can provide protection to transplanted hepatocytes from host immunorejection, and thus increase the viability of hepatocytes post transplantation. The existence of inadequately encapsulated microencapsule cause the fibrosis overgrowth around these capsules, resulting in ischemia and subsequent necrosis of the hepatocytes and decreasing hepatocyte viability.

ObjectiveTo investigate the characteristics of sexual behavior and HIV infections between normal men who have sex with men (MSM) and money boy (MB) in Jining city,so as to provide the basis for intervention.MethodsSentinel surveillance,VCT and respondent-driven sampling were adopted to recruit the target population,and the data was aualyzed with SPSS13.0.ResultsThe average age of normal MSM was 26.45 ± 5.8 and MB was 22.23 ± 3.3.The rates of single,marriaged and divorced about normal MSM and MB were 48.24％,45.53％,6.7％ and 85.4％,9.8％,4.9％ respectively.The educational level of normal MSM(74.8％ )was higher than that of MB(51.22％ ).MB group's rate of condom used(75.61％ ;51.22％ ) was higher than that of normal MSM ( 52.03 ％ ;32.79％ ).There was statistical significance in age,educational level,marital status and infecting rates of HIV between MB group and normal MSM group.ConclusionCompared with normal MSM,MB is the high risk population and bridge population of transmission of HIV.

Objective:To investigate the relationship between telomerase activity and the biological behavior of prostate cancer.Methods:The telomerase activity in prostate cancer tissues was detected by TRAP (telomeric repeat amplification protocol) ELISA which is based upon amplification of the initial telomerase product and detected by ELISA.Results:None of the 10 samples from normal prostates expressed telomerase activity.The thirteen of fifteen cases (86.0%) with prostate cancer presented telomerase activity.The activity of telomerase was associated with the pathological differentiation of prostate cancer.The two of twelve cases (17.0%) with benign prostatic hyperplasia (BPH) expressed telomerase activity,and the activity of telomerase was lower than prostate cancer.Conclusion:The telomerase acitivity may be related to the biological behavior of prostate cancer and can evaluate the malignant potential of prostate cancer.The presence of telomerase acitivity in some cases of BPH may indicate the presence of a minority of malignant cells,as yet clinically undetected,within the population of BPH cells.

ObjectiveTo study the protection of Chinese herbs on the ischemic brain of rats. Methods 75 Wistar rats were divided into 5 groups, Group 1 for false operation. For the other four groups, the common carotid artery was exposed then was ligatured and cut off, Group 2 for model. From the 20th hour after operation on,Group 3, 4, 5 were fed with complex prescription of Chinese medicine named Prescription 1, 2 and 3 once a day respectively. 3 hours after taking medicine, Groups 2-5 were put in the hypoxia environment for 1 hours, then taking the medicine for 7 days. On the 7th day after operation,the blood was taken from R. atria then the rats were killed and the whole right brains were cut off. Malonaldehyde (MDA), notric oxide synthetase (NOS) and superoxide dismutase (SOD) in the brain tissue and serum, and calcium in the brain were measured respectively. ResultsThe three prescriptions can decrease the quantity of MDA both in brain tissue and serum and the calcium in brain tissue(P<0.05-0.001).Prescription 1 can enhance the activity of SOD in brain tissue while the others can decrease the activity of NOS. The hippocampus cells show tidy, and the number of the necrotic cells decrease greatly among them, Groups 4 and 5 are better than Group 3.Conclusions Prescriptions 1-3 can protect the brain tissue of the rat form ischemic brain injury.

ObjectiveTo study the protective effect of Chinese Medical Formula Decoction on anoxic damage in cultured hippocampal neuronal cells from newborn rats. MethodsThe sera with Chinese Medicine (SCM-1,2,3) were collected from rats fed on Chinese Medical Formula Decoction Ⅰ,Ⅱ,Ⅲ(CMFD-Ⅰ,Ⅱ,Ⅲ) for 3 days,while the sera of rats which were fed with normal saline was collected as control. Hippocampal neuronal cells were obtained from dissociated cerebrella of 2 day old Wister rats. The cells were maintained in 5% CO2 humidified atmosphere at 37℃. After 7 days, the cells were grown in culture media containing SCM-1,2,3 and normal saline for 24 hours and in anoxic atmosphere for 1 hour. After anoxia, the cells were cultured for 24 hours. Culture media were collected and Malonaldehyde (MDA) and Lactate Dehydrogenase (LDH) in culture media were detected. ResultsThe survival neuronal cell rate in SCM-1 and 2 groups were significantly higher than control group. LDH and MDA in culture media of SCM-1 and 2 groups were lowed than control group. Conclusions There is a protective effect of CMFD-1 and 2 on anoxic damage in cultured hippocampal neuronal cells from newborn rats.
