OBJECTIVE To evaluate facial nerve decompression for Bell’s paralysis. METHODS The reports of facial nerve decompression for Bell’s paralysis were searched in PubMed and CHKD(China hospital knowledge database). Then an include criteria was made, and all the cases included were analyzed all together. The efficiency of different kinds of decompressions and time was discussed, while the steroid therapy was used as the control. RESULTS Five articles were include after search, in these reports there were 147 patients treated by surgery and 105 patients by steroid. The general rate of complete facial nerve recovery by decompression was 57.10 %, and 48.90 % by steroid therapy. The rate of complete recovery of facial nerve was 90.70 % if all segment decompression was done within 14 days after facial nerve paralysis, and it will decrease to 25.00 % if the surgery was done during 15 to 30 days after facial nerve paralysis. If the decompression was done during 15-30 days after facial nerve paralysis, the general recovery rate of mastoid and horizontal segment decompression was 45.70 %, but the all segments decompression was 25.00%. CONCLUSION Facial nerve decompression should be done within 14 days after facial nerve paralysis, the surgery done after 14 days will not improve facial nerve recovery. Till now there are no evidence can prove that all segment decompression be better than mastoid and horizontal segment decompression for Bell's palsy.

Objective:To evaluate the efficacy of occlusal rehabilitation in old patients with decreased vertical dimensions caused by serious attrition.Methods:Sixty-five patients with decreased vertical dimension caused by serious attrition were divided into 3 groups according to the defect of dentition and/or TMD.Group A included 42 patients with serious attrition and defection of dentition.Group B had 15 patients with heavy tooth wear,defection of dentition and TMD.Group C included 8 patients with serious attrition and functional TMD.All patients were conducted occlusal rehabilitation at increased vertical dimensions in normal intercuspital position(ICP) by removable denture with occlusal pad and removable occlusal splints.The time of follow-up visit of these patients ranged from 1.5 months to 9 years. Results:The masticatory efficacy of the patients was obviously improved,and all the symptoms of TMD were relieved.Furthermore,the symptoms of TMD were not observed after the treatment in patients without TMD.Conclusion:The results achieved by removable occlusal rehabilitation to aged people with serious attrition and decreased vertical dimension are satisfactory,and suggest that the occlusal rehabilitation is necessary for them.Furthermore,the removable occlusal rehabilitation can be acted as a reference and transition to permanent fixed occlusal rehabilitation.

Objective To investigate the clinical efficacy of TongluoShu Liquid in treating rheumatoid arthritis at early stage. Methods 100 cases were randomly recruited into a control group and a treatment group with 50 cases in each group. The treatment group was given TongluoShu liquid, 150ml / time, twice a day; and the control group was given Diclofenac Sodium Sustained Release Tablets (Deegan), one granule for each time, twice a day, and Methotrexate 7.5mg / time, once per week. Results In the treatment group, symptoms, signs and biochemical indicators were significantly improved, and the swelling of the soft tissue around the joints in stage Ⅰ and Ⅱ were also reduced. Besides, osteoporosis was controlled and the progress of destruction to the cartilage of stage Ⅲ was detained, though there was no statistical difference between the two groups after the treatment. Conclusion ShuTongluo liquid is a safe and effective medicine with less adverse reactions in treating rheumatoid arthritis.

Objective To analyze the MRI characteristics of vestibulocochlea neurovascular compression in patients with vestibular paroxysmia (VP) and to investigate the effect of the compression,its site and degree,on the occurrence of VP.Methods Twenty-eight cases of VP (VP group) and 28 cases of vertiginous patients other than VP (control group) were retrospectively reviewed.Three dimensional magnetic resonance angiography (3D-MRA) was performed and the data were used for neurovascular crosscompression (NVCC) analysis.The frequency and type of NVCC,the origin of the offending vessel and the distance between compression site and brainstem were compared between the two groups.Results The frequency of NVCC was 96.4％ (27/28) in VP group,with a significant difference compared with control group (13/28,46.4％ ;x2 =17.15,P ＜0.01).The most common NVCC type was vascular loop compression at vestibulocochlear nerve (15/35,42.9％).Anterior inferior cerebellar artery was the most common offending vessel (25/35,71.4％) in VP group.There were no significant differences between the two groups in the type of NVCC or the origin of the offending vessel.The frequency on the distortion and (or) displacement of vestibulocochlear nerve which was severely compressed by vessel in VP group (7/56,12.5％) was significantly higher than that in control group (0; P =0.013).The distance between compression site and brainstem was (8.57 ± 5.08) mm in VP group,and (8.93 ± 4.64) mm in control group,showing no significant difference.The ratio that the distance was less than 15 mm between compression site and brainstem in unilateral NVCC of VP group (100％) was significantly higher than unilateral NVCC of control group (7/10,P =0.033).Conclusions The VP patients have higher NVCC incidence and the most common NVCC type is vascular loop compression at vestibulocochlear nerve which is mainly caused by anterior inferior cerebellar artery.NVCC in VP patients mostly occurs in the central myelin portion of vestibulocochlear nerve.The site and degree of neurovascular compression may relate to the occurrence of VP.

Objective To explore the comprehensive approach of rhinoplasty using autologous costal cartilage and e-PTFE,and to observe the outcome and possible complications.Methods A 3-4 cm long costal cartilage was taken out mostly from the 6th or 7th rib and then divided into several parts and shapes.Structural reconstruction of the nasal tip was then done with these costal cartilage parts.Radix augmentation was conducted with e-PTFE.Results From Jan.2013 to Sept.2014,48 patients were treated with this method,all females,aged 22-35 years.36 of them had received rhinoplasty before,12 of them received none.Satisfying aesthetic contouring of the nasal tip and dorsum had been achieved in 45 patients.Deviation of the collumella and nostril asymmetry were found in 3 patients.Among all patients,no such complications as pneumothorax,hemothorax,infection,or hemotoma were observed.The scar on the donor site was not obvious.Conclusions Costal cartilage is sufficient,supportive and easily shapable,when applied to the structural reconstruction of the nasal tip,which can meet the demands of patients who prefer more outstanding and delicate nasal tip contouring.

Aim To study the protective effect of the compound flavones on chronic alcohol induced testicu-lar damage in mice. Methods One hundred SPF C57 BL/6 mice were randomly divided into 5 groups:normal control group, chronic alcohol group, alcohol+low-dose drug group, alcohol+high dose drug group, and drug control group. Chronic alcohol testicular inju-ry model in mice was established by intragastric admin-istration of increasing dose of alcohol every four weeks for 6 months, meanwhile compound flavone interven-tion was in process. The activity of super oxide dis-mutase( SOD) , the levels of malondialdehyde( MDA) and testosterone in testicular tissue were measured. HE staining was used to observe testicular histomorpholo-gy, and ultrastructure changes were detected by elec-tron microscope. Results In chronic alcohol group, MDA content was obviously increased, while SOD and testosterone levels were decreased compared with nor-mal control group ( P <0. 05 ) . In addition, germinal epithelium, support cells and sperm production at all levels showed degraded degeneration in chronic alcohol group. However, compound flavonoids could success-fully reverse alcohol-induced testicular damage in a dose-dependent way. Conclusion The compound of flavones may have therapeutic potential for alcohol-in-duced testicular injury through inhibiting lipid peroxi-dation and increasing the level of testosterone.
