BACKGROUND: The blocking treatment can improve the clinic symptom of facial spasm. But the site, depth and the angle of puncturing point are very difficult to be defined, which will seriously infect the curative effect.OBJECTIVE: To study the applied anatomy of the related structures of facial muscle for blocking the facial nerve, and to provide anatomical bases for accurate puncturing point and preventing complications.DESIGN: An observation study based on cadavers and making the mimic puncture and measuring the correlative structures with anatomical method.SETTING: Department of anatomy in a medical college.PARTICIPANTS: Totally 28 adult male cadavers(56 sides) were used and the correlative index were measured.METHODS: The blocking point was located at the convergent point of the interior edge of cartilage of the external acoustic canal, the anterior fringe of mastoid processes and the posterior fringe of mandible ramus, the needle must be thrust vertically to the median sagittal plane. The puncturing needle stopped until it was barred. A longitudinal incision was made from the puncturing point to mandibula angle, and skin, superficial fascia were cut separately. Then carotid superficial fascia was cut from the posterior fringe of parotidean. The facial nerve trunk and the posterior auricular artery were preserved in site. A blunt isolation was made along its incision. Jugular glomus was appeared. Then the correlative index were measured and dealt with statistics method.MAIN OUTCOME MEASURES: The puncturing point, angle and depth,the distance between facial nerve trunk and puncturing point, the position relationship between facial nerve and puncturing needle and the distance relationship between facial nerve and principal structures adjacent to it.RESULTS: The blocking point was located at the convergent point of the interior edge of the external acoustic canal, the anterior fringe of mastoid processes and the posterior fringe of mandible ramus, the needle must be thrust vertically to the median sagittal plane. On the left side, the puncturing depth was (19.91 ± 0.09) mm, On the right side, the puncturing depth was(19.28±0. 10) mm.CONCLUSION: The experimental study could provide accurate puncturing point, angle and depth for blocking the facial nerve and bring the blocking treatment into full play.

The cell killing effects and bystander effects of double suicide gene on pulmonary carcinoma cells were explored. Lung adenocarcinoma cells (A549) were transfected with different titers of adenovirus vector and followed with different concentrations of 5-FC after a recombinant adenovirus vector carrying CD/UPRT gene (Ad-CD/UPRT) was constructed. The cell viability was measured by MTT assay 4 days later. The cell viability was dropped to 30.57 %-8.62 % after 10 MOI of Ad-CD/UPRT transfected and 5-FC (10-1000 microg/mL) administration. Furthermore, Ad-CD/UPRT-infected A549 cells showed a profound neighbor cell killing effect in the same methods. These results suggested that Ad-CD/UPRT/5-FC system can effectively suppress growth of lung adenocarcinoma cells, which may provide a novel and powerful candidate for lung cancer gene therapy strategies.

Objective To investigate the effects of Thomas solution in combination with nitroglycerine of different concentrations on rat cardiac preservation for 8 h. Methods Thirty Wistar rats were selected,and Langendorff heart perfusion models were established.Rats were randomly divided into Thomas solution group,Thomas solution+4?10-6 mol/L nitroglycerine group and Thomas solution+4?10-5 mol/L nitroglycerine group(n=10).After hypothermic preservation(4 ℃)for 8 h,the cardiac function of each group was determined.Tissues of left ventricular wall were obtained,and changes of myocardial ultrastructure were observed by electron microscopy. Results Compared with Thomas solution group,the cardiac function was significantly improved and the myocardial ultrastructure injury was less severe in Thomas solution+4?10-5 mol/L nitroglycerine group after hypothermic preservation(4 ℃)for 8 h,while there was no significant difference in myocardial ultrastructure injury and cardiac function between Thomas solution group and Thomas solution+4?10-6 mol/L nitroglycerine group. Conclusion Thomas solution in combination with 4?10-5 mol/L nitroglycerine can significantly improve the preservation effects for isolated hearts in rats.
