Objective To compare curative effect of tibiofibular fractures treated by external fixation device and interlocking intramedullary nail.Methods A total of 121 patients with tibiofibular fractures were included in the study and were divided into external fixator group (56 patients) and interlocking intramedullary nail group (65 patients),according to diverse surgical approaches.The two groups were compared in indices of postoperative good-excellent rate,intraoperative blood loss,operation time,subsided time of postoperative swelling,hospital stay,fracture healing time,time of fixation removal and incidence of postoperative complications.Results The postoperative excellence rate in external fixator group and interlocking intramedullary nail group was 88％ and 89％,respectively (P ＞ 0.05).Compared with interlocking intramedullary nail group,the intraoperative blood loss was reduced more in external fixator group,with more evidently shortened operation time,subsided time of postoperative swelling and hospital stay (P ＜ 0.01).Fracture healing time and time of fixation removal,however,were significantly shorter in the interlocking intramedullary nail group than those in the external fixator group (P ＜ 0.01).Incidence of postoperative complications was 11％ in the external fixator group and 28％ in the interlocking intramedullary nail group (P ＜0.05).Conclusions External fixation device and interlocking intramedullary nail are both effective in treatment of tibial and fibular fractures.External fixation device with less damage to tissue is relatively more helpful to postoperative recovery.On the contrary,the interlocking intramedullary nail is relatively more conducive to fracture healing.

Objective To investigate the efficacy of microwave ablation for big liver cancer by using laparoscopy.MethodsFrom August 2000 to October 2006,28 patients with large big liver cancer(over 5 cm in diameter)was treated by microwave ablation under the guidance of a laparoscope.On each tumor nodule,3 to 5 electrode insertions was applied.And for each lesion,the treatment was performed for 1 to 3 times.Results The complete ablation rate of this series was 78.6%(22/28),and the rate of local recurrence was 35.7%(10/28).1-,3-,and 5-year survival rates were 75.0%(21/28),57.1%(12/21),and 36.4%(4/11),respectively.Conclusions Laparoscopic microwave ablation is safe and effective for liver cancer.The procedure can increased the efficacy of the microwave by enlarging the extent of the ablation.

Objective To discuss the expression of cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) in adenomyosis and its clinical significance. Methods The expression of COX-2 and VEGF was examined by immunohistochemistry SP method, in ectopic endometrium and eutopic endometrium, compared with normal endometrium. Results (1) COX-2 expression in ectopic, eutopic endometrium with adenomyosis was significantly higher than that in control group (P<0.05). No statistically significant difference was found between ectopic endometrium and eutopic endometrium group with adenomyosis (P0.05).(2) VEGF expressions in ectopic, eutopic endometrium with adenomyosis were both significantly higher than that of control group (P<0.05); no statistically significant difference was found between ectopic endometrium and eutopic endometrium group (P0.05).(3) COX-2 and VEGF had the positive relativity in the ectopic endometriumal expression of adenomyosis patient (P<0.05). Conclusion COX-2 and VEGF may play a key role in adenomyosis. Both may have close relation in angiogenesis and may provide new targets for therapy of adenomyosis.

The molecular delivery vectors used in gene therapy need provide the features of safety,stability, efficiency and capacity. The current studies on the structure and action mechanism of pRNA, a packaging RNA of phage?29, showed that pRNA with multiple binding sites can through cell membrane easily and escort exogenous molecules to target cell, without inducing immune reaction. As an ideal nano-scale gene therapy vehicle, pRNA presents a promising application in delivering multiple therapeutic components to detect and treat human diseases.

The aim of this study is to investigate the effect of fluoxetine (FLX) on the expressions of BDNF and Bcl-2 in the hippocampus, the amygdala and the prefrontal cortex of conditioned fear (CF) model mice. Forty eight mice were randomly divided into three groups, normal control group, CF stress group and FLX-pretreated CF group. The FLX-pretreated CF group was given FLX (10 mg x kg(-1) x d(-1)) for 7 days before CF stress. After CF stress model was established, all mice were given behavioral experiments to test whether FLX impaired or improved the auditory and contextual fear conditioning. Then mice were sacrificed. The expressions of BDNF and Bcl-2 were detected by Western blotting. The results showed that the freezing time of FLX-pretreated CF group was significantly lower than that of CF group; FLX pretreatment up-regulated the expression of Bcl-2 in the hippocampus at 1 d after CF stress (P < 0.001), but no significant differences was observed at 7 d; BDNF significantly increased in the hippocampus at 7 d (P < 0.001), but no differences at 1 d; the expressions of BDNF and Bcl-2 in the amygdala and the prefrontal cortex were of no obvious differences between CF group and FLX-pretreated CF group at 1 d or 7 d after CF stress. Parallel to these changes, pretreatment with FLX could affect histopathologic changes induced by CF stress. Furthermore, the results indicated that FLX pretreatment could protect against CF stress-induced neurological damage via the activation of BDNF and Bcl-2 in hippocampus.

Saw palmetto fruit extract (SPE), as a herbal product, is widely used for the treatment of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). Recent studies show that SPE also has some therapeutic effects on chronic prostatitis, prostate cancer, sexual dysfunction, and so on. This article presents an overview on the application of SPE in the treatment of BPH, prostate cancer, and chronic prostatitis/chronic pelvic pain syndrome, with a discussion on its action mechanisms.
