OBJECTIVETo investigate the morphology change of stomatognathic muscles after zygomatic plasty combined with mandibular angel plasty.

METHODS3D-CT facial soft tissue measurement was performed pre-operative and at 10 days,3 months post-operatively in 59 cases with prominent malar-complex and mandibular angle. The q test (Newman-Keuls method) was used to analyze the variance.

RESULTSThe cross sectional area of masseter muscle and medial pterygoid muscle were both increased at 10 days, reduced at 3 months post-operatively (P < 0.05). The masseter muscle and medial pterygoid muscle cross sectional areas were (4.73 +/- 0.21) cm2 and (3.24 +/- 0.21) cm2 at anterior nasal spine plane, respectively; the pterygoid muscle cross-sectional area was (1.37 +/- 0.35 ) cm2 at the root of coronoid process plane, showing significant difference, when comparing with those before operation (P < 0.05). Lateral pterygoid muscle and temporal muscle had no statistical difference between the pre-and 10 days post-operatively(P > 0.05), however, the temporal muscle was reduced while the lateral pterygoid muscle was increased at 3 months post-operatively. The temporal muscle cross-sectional area was(2.35 + 0.25) cm2 at coronoid process plane; the temporal muscle and lateral pterygoid muscle cross-sectional areas were (1.00 +/- 0.16) cm2 and (3.54 +/- 0.61) cm2 at the root of coronoid process plane, which were significantly different from those before operation (P < 0.05 ).

CONCLUSIONSBecause of osteotomy, muscles attached position are changed in the short term after zygomatic plasty combined with mandibular angel plasty. Masseter muscle and medial pterygoid muscle are inevitably injuried during the operation. With the postoperative recovery, muscles have adaptive changes which reduced compared with those before operation after their reattachment. Zygomatic plasty can cause temporal muscle atrophy;while the lateral pterygoid muscle is rarely involved, the cross sectional area had no statistical difference between the pre- and 10 days post-operative, and the cross sectional area increase at 3 months post-operatively may be due to a compensational enlargement.

Objective To summarize the clinical experience of endovascular intervention for intra-cranial aneurysms, especially in the respect of the technique and management of intra-operative complications. Method The clinical data of 60 patients with intra-cranial aneurysms treated with endovascular intervention in the past 3 years were analyzed. The relevant literature especially with regard to the practical technique described was reviewed so as to potentiall minimize and properly manage the intra-operative complications. Results A total of 69 sacciform aneurysms and one dissecting aneurysm located at left vertebral artery (VA) were detected by using digital subtraction angiography (DSA) in 60 patients. There were 65 saccular aneurysms obliterated with constructive approach, and five of them treated with stent-assisted technique and four of them treated with ballon-assisted technique. The VA dissecting aneurysm was obliterated with coils by deconstructive approach with complete occlusion of its parent vessel. There were a total of 53 complete occlusions of aneurysms accounted for 76.81% of 69 sacciform aneurysms in 51 patients ( 85 % ) and eight subtotal occlusion of aneurysms (95 % ～ 99 % occlusion) accounted for 13.56% of total sacciform aneurysms in five patients (8.47%) and four incomplete occlusion of aneurysms ( ＜ 95% occlusion) accounted for 6.78% of total sacciform aneurysms in three patients (5.08%), and one was failure in operation. The rupture of aneurysms occurred during operation in4 patients (6.78%). Two senile patients suffered from intra-opeartive symptomatic thromboembolisn. One patient had stent shifting and spring coil dislocated and moved into the M3 segment of the ipsilateral MCA. Vasospasm occurred in 15 patients during operation, and most of them received endovascular intervention 3 days after the initial ictus. The rate of good recovery was 93.3% at discharge from hospital (the modified Rankin Scales, mRS＜ 2). There were 55 patients followed up for up 24 months after discharge, and excellent recovery rate was found in 51 patients ( mRS ＜ 2), and 3 died.During the follow-up period, no aneurismal recanalization or rupture was noticed in all patients. Conclusions The endovascular intervention is a safe and effective approach to the intra = cranial aneurysms. Advances in the skill of technique and proper management will decrease the complications during operation and improve the prognosis of patients.

Objective To study the effects of the HBV x gene (HBx) on the biological characteristics and the expression of DNA repair enzyme hMTH1 mRNA of the L02/HBx transgene cell model. Methods Light microscopy was used to observe the morphologic characteristics of gene-transfected cell strain Lff2/HBx that stably expressed the HBx protein and the control groups of L02 and L02/PcDNA3.1. The changes of L02/HBx on the proliferation, cell cycle and apoptosis were observed by MTT assays and flow cytometry analysis respectively. Moreover, the malignant transformation of L02/HBxwas assayed by colony formation in soft agar and the expression of DNA repair enzyme hMTH1 mRNA was assayed in each group by real-time qPCR. Results Inversion phase contrast microscope showed that the morphologic characteristics of L02/HBx had changed obviously compared with control groups. The MTT showed that L02/HBx proliferated more quickly and flow cytometry analysis indicated that HBx could accelerate the progression of cell cycle and inhibit apoptosis. Colony formation in soft agar demonstrated that the rate of colony formation of L02/HBx was remarkably higher than the L02 and the L02/peDNA3. 1 cells (P<0. 05). The real-time qPCR detection showed that the expression of hMTH1 mRNA in L02/HBx was significantly higher than that in the control groups ( P < 0. 05 ). Conclusion HBx could play an important role in the malignant transformation of L02/HBx and the over expression of hMTH1 mRNA.
