    Objective To investigate the application and value of MSCT multimodal three-dimensional (3D) reconstruction in cochlear implantation. Methods ① The membranous structures with 3D imaging of cochlea, vestibular, semicircular canal and temporal bone transparent imaging were constructed with a double threshold reconstruction technique, where the anatomical relationship between ossicles, inner ear and temporal bone were displayed. ② The facial nerve reconstruction displayed the path of the facial nerve. The ultrastructure showed the facial nerve, facial nerve recess, posterior wall of the external auditory canal and the structure of chorda tympani nerve and neighboring structures. ③ The distance between promontory plane vertical segment of the facial nerve and chorda tympani nerve was measured. Results Of the 83 patients recruited in this study, 11 had inner ear malformation. Of them, 2 had Mondini malformation, 2 had semicircular canal malformation, 2 had common cavity malformation, 1 had internal auditory canal stenosis, and 4 had enlarged vestibular aqueduct. The distance between normal structure of cape plane vertical segment of the facial nerve and chorda tympani nerve was 0.27±0.057 cm at the left-side and 0.28±0.068 cm at the right-side. An intact structure of the implanted electrodes was clearly showed in 5 patients in the post-operative examination. Conclusion The 3D multimodal reconstruction technique is useful in providing ultrastructure imaging of the middle and inner ear, which is important for surgeons in pre-and post-operative evaluations of the success and potential risk factors for performing cochlear implantation.

    Objective To explore the clinical application of mastoid cavity packing by retroauricular pedicle fascia-temporalis muscle flap in secondary open radical mastoidectomy. Methods A total of 20 patients (20 ears) who had undergone open radical mastoidectomy received secondary open radical mastoidectomy due to long-time wet seepage of their ears. Of them, 10 received open radical mastoidectomy (RM) and 10 received open radical mastoidectomy with mastoid packing operation (CWDM). All CWDM operations adopted retroauricular pedicle fascia-temporalis muscle flap mastoid cavity packing. Results All cases were followed up for 2 years. The average time of ear drying was (58.4±4.45)d and (29.6±2.37)d in RM group and CWDM group, respectively. The average return visit frequency was (17.1±2.33) and (6.1±1.52) times in RM group and CWDM group, respectively. One case in the RM group had wet ear continuously. There was no wet ear and relapsing after operation in the CWDM group. CWDM group had a shorter ear drying time and lower return visit frequency than the RM group (P<0.001). Conclusion CWDM is superior to RM in ear drying time, return visit frequency and relapsing after operation and other indicators.

    Objective To explore the surgical strategies and techniques in the management of refractory cerebrospinal fluid (CSF) otorrhea. Methods Combined subtemporal trasnscranial and transmastoid approach was performed to repair the middle cranial fossa defects in 11 patients with posttraumatic CSF otorrhea. Results (1) Mastoid probe was not required in 5 cases. Due to comminuted fractures of mastoid process, 2 cases needed titanium plate fixation before the bone flaps were removed. In the other 4 cases with serious mastoid fracture, the pieces were collected and refilled back to the defect, and fixed together with longissimus by biological glue. (2) The brain tissues herniation and/or exposed mastoid mucosa via large skull base defects were observed intraoperatively in 6 cases. (3) The ossicular chain was intact in 3 cases, disappeared in 2 cases, and not inspected in 4 cases; the otosteon (malleus) was missed in 2 cases. No recurrence was recorded during the follow-up of 2-11 years. Conclusion (1) A combined supra-infratentorial approach, with an incision incorporating both the middle skull base and mastoid process, is advisable for the management of CSF otorrhea with complex fractures, especially with unstable fractures involving the mastoid process. (2) Postoperative rhinorrhea could be prevented by tamponade of tympanic cavity, especially, the eustachian tube, in addition to obliteration of the external auditory canal during surgical repair of CSF leaks in patients with complex fractures and hearing loss. (3) Inadvertent injury to petrous segment of the internal carotid artery should be avoided during surgical manipulations near tympanic cavity and eustachian tube.

    Objective To observe the effect of high-resolution computed tomography (HRCT) grading of low middle fossa tegmen plate on the elimination of diseased tissue in epitympanum and to investigate the grading standard of low middle fossa tegmen plate. Methods The CT images obtained from 87 chronic otitis media (COM) cases were subjected to coronal reconstruction. A horizontal tangent L1 at the highest point along the upper wall of external auditory canal, a horizontal tangent L2 at the highest point of the semicircular canal structure, and a horizontal tangent L3 at the lowest point along the middle fossa tegmen plate were created to measure the distance between L1 and L2, L1 and L3, and to calculate the r value (b/a). The r value was used to divide the low middle fossa tegmen plate into five grades: non-low, mild, moderate, severe, and absolute low. Pre-operative evaluation and postoperative results were compared. Results Surgeons had different opinions on the r value: (1) If r < 1/4, the low middle cranial fossa cover identified by the Radiation Department could not be accepted. (2) If 1/4 ≤ r < 1/3, the low middle cranial fossa cover identified by the Radiation Department could be accepted, but it was not mentioned in the operation record. (2) If 1/3 < r ≤ 1/2, wearing was found at the bottom wall of the middle fossa tegmen plate upon clearing the diseased tissue, and the operation would be affected because of bleeding. (4) If 1/2 < r ≤3/4, the surgeons were able to identify the low middle fossa tegmen plate before operation; but some cases' back wall of the external auditory canals could be preserved after the diseased tissue in the epitympanum was cleared. (5) If r > 3/4, the surgeons experienced difficulty in finding the trum tympanicum and pathway behind the ear because the low middle fossa tegmen plate wore down the back wall of external auditory canal. Conclusion The r value can be used to divide the low middle fossa tegmen plate into five grades: non, mild, moderate, severe, and absolute low. Mild grade has no effect on the removal of lesions,moderate grade makes the removal of lesions difficult, severe grade requires destruction of the back wall of external auditory canal, and absolute low grade means wearing down of the back wall of external auditory canal is inevitable.

    Objective To study the real necessity of antibiotics in septoplasties. Methods A total of 180 patients underwent septoplasty and were randomly divided into group A (n=60), group B (n=60) and group C (n=60). Group A was without antibiotics, group B and group C were respectively given cephradine(3.0 g) or cefamandole (1.5 g) both in the anesthesical induction and post-operatively for 3 days. Results There were 6 cases(10.0%) infected in group A, 7 cases(11.7%) infected in group B, and 5 cases(8.3%) infected in group C. The infection rate had no significant difference in the three groups (χ2=0.370, P=0.831). Conclusion In peri-operative period of septoplasty, routine prophylactic use of antibiotics can not reduce the incidence of post-operative infection.

    Objective To study the expression of epidermal growth factor-like domain 7(EGFL7) in nasopharyngeal carcinoma(NPC), and to investigate its correlation with microvessel density(MVD) and lymphatic vessel density(LVD) and its relationship with the invasion and metastasis of NPC and its possible mechanism. Methods The immunohisto chemical method was used to detect EGFL7 expression of 40 cases of nasopharyngeal carcinoma and 20 cases of nasopharyngitis; MVD and LVD were detected by antibody CD31 and D2-40 antibody for immunohistochemistry in the experimental and control groups, and to analyze the correlation of EGFL7 expression and tumor grade and MVD and LVD. Results The experimental group and the control group were of EGFL7 expression, but in the experimental group EGFL7 expression rate was higher than that of control group (P<0.05); EGFL7 expression and MVD was positively correlated in the experimental group, but LVD did not; in the experimental group, lymph node metastasis of LVD was significantly higher than those without lymph node metastasis of (P<0.05); in the experimental group, EGFL7 expression had no correlation with patient gender, age and EB virus antibody (P>0.05) but had some correlation with clinical stage and lymph node metastasis(P<0.05). Conclusion EGFL7 has no dual function on blood vessels and lymphatic vessels, it only expresses in endothelial cells and nasopharyngeal carcinoma cells. EGFL7 is closely associated with the growth and invasion and metastasis of nasopharyngeal carcinoma (NPC), it may become one of the markers reacting nasopharyngeal carcinoma metastasis and prognosis.

    Objective To investigate the correlation of tumor suppressor in lung cancer 1 (TSLC1) and laryngeal squamous cell carcinoma, in order to provide a theoretic basis of oncogenesis, diagnosis and treatment of laryngeal cancer. Methods Paraffin-embedded specimens were collected from 45 cases of laryngeal squamous cell carcinoma, 8 of which had lymphatic metastasis. Another 20 specimens from normal adjacent tissues served as controls. The expression of TSLC1 was detected with immunohistochemical staining (PV-6000). The relation between TSLC1 expression and other clinicopathological parameters was analyzed with SPSS 10.0. Results The positive expression of TSLC1 was 17/45 (37.8%) in specimens of laryngeal squamous cell carcinoma, which was significantly lower than in specimens of normal adjacent tissues (15/20, 75%), (χ2=7.68, P<0.01). Loss of TSLC1 expression was correlated with the clinical stage, tumor differentiation and lymph node metastasis (χ2=4.15, 6.11, 4.11, P<0.05), but not correlated with patients' age, gender, or location of primary laryngeal carcinoma (χ2= 0.25, 0.09, 1.0, P>0.05). Conclusion Loss of TSLC1 expression is frequently observed in laryngeal squamous cell carcinoma, which is significantly correlated to the clinical stage, tumor differentiation and lymph node metastasis. The down-regulation of TSLC1 expression may correlate with the occurrence and invasion of laryngeal squamous cell carcinoma, but more studies are needed to verify the hypothesis.

    Objective To investigate the role of CT scan as an optimal approach in the diagnosis of foreign bodies in the cervical esophagus, and to explore the different treatment options based on the scan results. Methods Clinical data of 179 patients admitted to our department due to upper esophageal foreign body during May 2011 and Oct. 2014 were retrospectively analyzed. All cases had symptoms of dysphagia, swallowing obstruction and pain. The diagnosis of upper esophageal foreign body was confirmed via X ray or HRCT examination. The foreign bodies were removed with different methods based on results of CT scan. Results The foreign bodies were removed with rigid esophagoscope under general anesthesia in 68 cases, with electronic gastroscope under topical anesthesia in 60 cases, with lateral neck incision in 10 cases, with 16# Foley catheter under no anesthesia in 12 baby patients. Another 29 patients with fishbone received no treatment because the foreign bodies and symptoms disappeared within 12 hours. Conclusion Eating too fast or being absent-minded during dinner are the major causes of esophageal foreign bodies. Correct evaluation of the nature, size, position of the foreign bodies, and damage they might do to patients, as well as timely management are key to treat cervical esophageal foreign bodies and avoid complications.

    Objective To observe the protection role of the sirtuin 1 (SIRT1) towards the retinal pigmented epithelium(RPE) cells following exposure to oxidative stress. Methods The rates of proliferation and apoptosis, levels of intracellular reactive oxygen species(ROS) and cell senescence of RPEs, induced by oxidants (H2O2), were evaluated. Results The results revealed a down-regulation of SIRT1 expression during oxidative stress. Furthermore, SIRT1 activator resveratrol (RSV) and inhibitors nicotinamide (NA) were respectively treated on RPE cells following exposure by H2O2 intervention; the expression of SIRT1 gene were detected by RT-PCR technology after RNA interfering on SIRT1. The experiments indicated that cell proliferation, apoptosis and ROS levels were significantly different compared with the control group after intervention by H2O2, and cell senescence were significantly increased; NA was significantly increased the toxicity of H2O2, however RSV had the opposite anti-cytotoxicity of H2O2; RT-PCR analysis showed that SIRT1 levels were significantly reduced. Conclusion These results therefore suggested that down-regulation of SirT1 expression during oxidative stress, further investigation indicated that SIRT1 protected RPEs from oxidative stressinduced damage. Appropriate increase of the activity of SIRT1 may be a therapeutic strategy to delay AMD.

    Objective To evaluate meibomian gland dysfunction after phacoemulsification surgery. Methods Fifty-eight eyes of 58 patients underwent phacoemulsification and were evaluated the OSDI, lid margin abnormalities, superficial punctate keratopathies (SPK), tear film break-up time (BUT), Schirmer test, lower tear meniscus height, depth, and area using anterior segment optical coherence tomography, and meibum expressibility pre-operatively and at 1 month and 3 months post-operatively. Results The OSDI were worse at 1 month and 3 months post-operatively (10.7±7.9, 25.7±7.9, 27.9±12.1, P<0.05 and P<0.05, respectively). Lid margin abnormalities were significantly increased (1.6±1.0, 2.0±1.2, 2.5±0.9, P<0.05 and P<0.05, respectively) and BUT decreased post-operatively (6.6±3.1, 4.3±1.9, 4.1±2.2, P<0.05 and P<0.05, respectively). Meibum expressibility decreased at 3 months post-operatively (1.8±0.9 vs 2.2±0.7, P<0.05); however, SPK, lower tear meniscus height, depth and area and the Schirmer test did not significantly change post-operatively (P>0.05). Conclusion Meibomian gland function may be altered without accompanying structural changes after phacoemulsification surgery.

    Objective To evaluate the effect of glycosylated hemoglobin on dry eye in patients with type 2 diabetes mellitus. Methods A total of 140 patients with type 2 diabetes mellitus were collected and divided into two groups: poor in glucose control group (n=70) and good in glucose control group (n=70), according to the level of glycosylated hemoglobin A1c (HbA1c). All patients were inquired about dry eye svndrome and received the examinations as follows: Schirmer I test (SIt), tear break-up time (BUT) and corneal fluorescein staining (FL). Results The elderly and male patients of poor in glucose control group showed higher incidence of dry eye syndrome than that of good in glucose control group, showing a significant difference between two groups (P<0.05). The elderly patients of poor in glucose control group showed lesser SIt and faster BUT than controls (P<0.05); there were no differences among SIt, BUT in young and middle patients of two groups. HbA1c level was positively correlated with dry eye svndrome, and negatively correlated with SIt, BUT. Conclusion The HbA1c level was correlated with dry eye in elderly patients with type 2 diabetes mellitus. It has great clinical value by controlling the glycosylated hemoglobin levels on patients with type 2 diabetes mellitus.

    Objective To investigate the effectiveness and safety of retinal photocoagulation(RP) in combination with vitrectomy in treatment of proliferative diabetic retinopathy(PDR). Methods The clinical data of 79 patients (79 eyes) with PDR treated by RP and vitrectomy in our hospital during March 2010 to March 2014 were retrospectively analyzed. Results In a follow-up of 12 months after the operation, 61 eyes (77.22%) improved their post-operative visual acuity, 15 eyes (18.99%) had the same vision and 3 eyes (3.80%) had deterioration. After vitrectomy of 1 month, 2 eyes had the iop elevated over 30 mmHg, 1 eye had neovascular glaucoma (NVG), and 1 eye had retinal detachment. After vitrectomy of 3 months, 2 eyes had fro vitreous hemorrhage again. After vitrectomy of 12 months, 2 eyes had silicone oil emulsification occurred secondary glaucoma. Conclusion Angiography after vitrectomy can be targeted to treat RP. It can avoid excessive photocoagulation and can prevent photocoagulation insufficiently, improves in vision at the same time with few complications and high safety, is an effective method for PDR.

    Objective To probe the classification of retinal hemorrhage(RH) in vaginal delivery term newborns according to digital wide-angle retinal imaging device(RetCam-3 ). Methods A total of 1 021 healthy full-term normal delivery newborns(2 042 eyes)were enrolled in this study.A digital wide-angle retinal imaging device(RetCam m) was used to examine the subjects at about 3 days after birth. Newborns with RH were reexamined after three, four and six weeks. RH was classified according to the location of RH and degree of hemorrhage in macular by RetCam-3. Results In 1 021 cases of newborns,retinal hemorrhages were found in 165 infants(17.14%).Within these 165 infants,155 infants(16.16%)wereⅠdegree retinal hemorrhage, 9 infants(0.88%) were Ⅱdegree retinal hemorrhage and 1 infant (0.01%) was Ⅲ degree retinal hemorrhage. The average time of second stage of labor in newborns without RH was 49.81±5.3 minites. The average time of second stage of labor in newborns with RH was 51.13±6.12 minutes. Newborns with RH had longer second stage of labor than those without RH. The difference was statistically significant (t=2.839, P=0.005). Conclusion According to the result of RetCam-3 of 2 042 eyes, we classify RH in degreeⅠ,Ⅱ and Ⅲ. RH of DegreeⅠis located in the superficial retina and resolves itself within three weeks after birth. RH of DegreeⅡ is located in the superficial retina including macular and resolves itself within six weeks after birth. RH of Degree Ⅲ is located ahead of retina including macular and does not resolve itself within six weeks after birth.Prolonged second stage of labor may play roles of risk factor in retinal hemorrhage.
