Objective To discuss the technique and value of preoperative reformatting with three-dimensional computed tomography technique for C_2 pedicle screw track.Methods GE Light Speed 16 Pro spinal CT scans of 15 adult dry vertebrae were loaded into an imaging station (software ADW4.2).Two methods of C_2 pedicle screw techniques were analyzed through virtual screw trajectory by VR (volume rendering) and MPR (multiple planar reformatting) techniques,in method A,screw entry point was the intersection between the media-vertical and the cranial line of C_2 inferior facet joint,in method B,the screw track was from the cranial and medial quadrant of the dorsal part of C_2 inferior facet joint.Results The screw track could be observed dynamically from any plane.Two vertebrae were ob- served with smaller height in isthmus and the medial edge of the transverse foramen since no space was a- vailable for the screw.The screw trajectories data were compared between method A and method B,which showed that the angles towards the cephalad (in sagittal plane) and midline (in transverse plane) were bigger in method A than in method B (P<0.05,0.01),but the safe screw diameter was smaller in method A than in method B (P<0.05),and there was no difference of the screw length between the two methods(P<0.05 ).Conclusion In this research,the individual C_2 pedicle screw entry points, screw diameter and security screw angle can be simulated,and the screw track can be observed dynami- cally to make sure if it transits the bone structure completely.Preoperative three-dimensional computed tomography reformatting for pedicle screw track is of great value in clinical and basic researches.

Objective To make a preliminary investigation and summary of the technique and efficacy of the novel intracranial stent, Enterprise, together with hydro-detachable coils for the treatment of very small intracranial wide-necked aneurysms (diameter<3 nun and body-to-neck ratio<1.5). Methods Six cases with very small intracranial wide-necked aneurysms were treated with Enterprise stents and hydro-detachable coils. In 5 cases the Enterprise stent was implanted to cover the neck of the aneurysm, which was followed by the introduction of a microcatheter into the aneurysmal sac through the stent mesh to stuff hydro-detachable coils in order to fill the aneurysmal sac. In the remaining case, the microcatheter was placed into the aneurysmal sac before the Enterprise stent was inserted to embolize the aneurysm. Postoperative follow-up was conducted for 3-6 months. Results The operation was successfully completed in all 6 patients, with the implanted stents being in right place. The parent arteries remained patency in all patients. No complications occurred. Complete occlusion of aneurysmal cavity was obtained in four cases, and the occlusion degree of the aneurysmal cavity above 95% was seen in 2 cases. After the procedure, all the patients recovered well. Neither rebleeding nor symptoms related to thrombosis occurred during a clinic follow-up of 3-6 months. Conclusion Endovasculur embolization with Enterprise stent together with hydro-detachable coils is a safe and effective method for the treatment of very small intracranial wide-necked aneurysms. However, its long-term effect needs to be further observed.

Hepatitis B virus (HBV) infection is a global public health problem which greatly threatens human health. Paternal-fetal vertical transmission (P-FT) is one of the leading causes of persistent HBV infection, and has a transmission rate similar to that of mother-to-child vertical transmission. In recent years, P-FT has been attracting more and more attention and has become a hot research topic at home and abroad. It has been confirmed that P-FT occurs via sperm, but the mechanism remains unknown. Studies have shown that a high HBV DNA load in serum and semen and positive serum HBeAg are the major risk factors for the occurrence of P-FT. Random integration of HBV DNA into sperm can affect sperm quality, cause male infertility, and even affect the maternal pregnancy outcome. Currently the most important measure to block P-FT is pre-pregnancy intervention, including antiviral therapy for the father and active immunization for the mother.
