For the treatment of rhinosinusal malignant tumors involving the anterior skull base, nasal endoscopic surgical technique has a comparable short-term curative effect, lower complications, and better quality of life compared with anterior craniofacial resection. Although the scope and indications of nasal endoscopic surgical technique are expanding, present evidence regarding these issues is low. Furthermore, there is still a lack of unified surgical indications and methods, and the curative effect also needs to be verified.

It is very important to select the appropriate surgical approach in the operation of endoscopic skull base surgery. There are two principles: (1) the field of view should be well exposed; (2) the important neurovascular injury should be avoided. In the endoscopic endonasal approach to the lateral midline skull base, the anatomical structures of the pterygoid process, the vidian canal, the foramen rotundum, the foramen ovale and the eustachian cushion are relatively fixed. By the endoscopic endonasal transpterygoid approach, we can handle the pterygopalatine fossa, infratemporal fossa, cavernous sinus, Meckle cavity, paraclival to cavernous segment of internal carotid artery, petroclival region, petrous apex, eustachian tube area, and the upper parapharyngeal space. Pterygoid process can be used as the anatomical landmark for endoscopic skull base surgery and be chosen as the operation center for inward and outward expansion. Making full use of the space location, increasing the sense in the operation of three-dimensional space, is helpful in expanding the endoscopic skull base surgery.

Objective To evaluate the clinical application of image-guided endoscopic techniques in the management of nasal sinus, skull base and orbital disease. Methods Retrospective review was performed in 751 transnasal endoscopic surgeries with the help of the image navigation system, including 565 cases with Medtronic Stealth Station^TM optical based system and 186 cases with Medtronic Fusion electromagnetic system. The accuracy of image navigation system, preoperative registration time, benefits and undesirable problems of intra-operative navigation and surgical complications were analyzed. Results Both platforms had been shown to be accurate to within 2 mm. The benefits of navigational technology were evaluated by VAS scores, which decreased to(8.3±1.2). The anatomic sites were frontal sinus, optic nerve and carotid artery,which the best guided effects applied by navigational orientation. The major undesirable problems in navigation procedures were image-drifting, failing to real-time orientation, and failing to registration. All surgeries completed successfully without any complications. Conclusion The image-guided techniques can assist endoscopic surgeons to identify surgical markers with precision and eliminate anatomic illusion possible under endoscopy. The incidence of undesirable problems in navigation procedures was low. The experience of surgeon for endoscopic and navigational operation was very important under this situation.

Objective To explore and discuss the treatment strategy of benign osteogenic tumors with involvement of nasal skull base area, including osteoma, ossifying fibroma and fibrous dysplasia. Methods 140 patients with benign fibro-osseous lesion of naso-siunses were treated surgically, including 116 cases of osteoma, 14 cases of ossifying fibroma and 10 cases of fibrous dysplasia. Surgical methods include simple nasal endoscopic surgery in 95 cases, image navigation assisted nasal endoscopic surgery in 24 cases, nasal endoscopy combined with external nasal approach in 21 cases. Results No serious complications occurred in all cases who underwent different operations. All osteomas were completely removed. Ossifying fibromas were completely removed in 12 cases, except 2 cases with residual lesions. All cases of fibrous dysplasia were received the palliative surgery, and the facial appearances of the patients were recovered and the compressive symptoms of the surrounding tissues were relieved. The follow-up period ranged from 6 to 36 months. No recurrence was found in patients with osteoma; recurrence occurred in 2 cases ossifying fibroma; the symptoms of fibrous dysplasia get different degree of ease, except 1 patient with visual loss remained unchanged. Conclusion Osteoma, ossifying fibroma and fibrous dysplasia are common benign osteogenic lesions of paranasal sinuses. High resolution CT and(or)MRI are important means for early diagnosis. Endoscopic sinus surgery under the guidance of image navigation or combined with external nasal approach is an effective method for the treatment of these diseases. The choice of operation opportunity and surgical methods should be based on the type of lesion, the patients symptoms, the location and scope of the tumor.

Objective To analyze the feasibility cochlear implantation(CI)for deaf children with abnormal white matter and to compare their hearing levels, speech function, cognitive abilities before and after surgery. Methods Six deaf children with abnormal white matter among 425 patients who had received CI from November 2012 to April 2015 in our department were selected as the experimental group, and another 6 patients with normal white matter at almost the same time were enrolled as the control group. The outcome of speech functions in the experimental group before and after surgery were compared. Statistical analysis was conducted by repeated measures analysis of variance, Rank sun test, t test and Chi-squared test with the hardware SPSS19.0. Results (1) Statistical significances in meaningful auditory integration scale(MAIS), categories of auditory performance(CAP)and speech intelligibility rating(SIR)were found 山东大学耳鼻喉眼学报31卷2期 -董健菲,等.合并脑白质异常聋儿人工耳蜗植入后听力言语及认知能力评估分析 \=-in the experimental group before and after surgery. (2) No statistical significances in hearing threshold before and after surgery between the two groups were found. (3) No statistical significances in MAIS,CAP and SIR between the two groups were found before and after a 6-month follow-up, but statistical significances were found after a 12-month follow-up. (4) Statistical significances in Wechsler young children scale of intelligence(C-WYCSI)were found between the two groups after a 12-month follow-up. Conclusion Speech function of deaf children with abnormal white matter was significantly improved after CI. The hearing levels of deaf children with abnormal white matter are basically the same compared with deaf children with normal white matter after CI. As are result, CI could be conducted after strict examinations before operation. Nevertheless, speech functions and cognitive abilities between them were still different after a 12-month follow-up. Therefore, adequate communication with parents of deaf children whose white matter are abnormal should be done before surgery.

Objective To explore the application value of inferior nasal concha sequential surgery in the treatment of chronic hypertrophic rhinitis, so as to provide a optimized inferior nasal concha surgical protocol for clinical treatment. Methods A total of 109 patients with hypertrophic rhinitis were randomly enrolled and divided into sequential surgery group(n=54)and single plasma treatment group(n=55). The severity degree of rhinobyon, nasal stuffy, rhinocnesmus, mycteroxerosis, nasal pain, and nasal discomfort, visual analogue scale(VAS)score and Lund-Kennedy endoscope scores were recorded 2 weeks, 2 months and 6 months after the treatment. Results There was no significant difference between two groups in Lund-Kennedy endoscope score after treatment for 2 and 6 months respectively(P>0.05), but the difference was significant after 2-week treatment(P<0.05). Sequential surgery group was markedly lower in the total Lund-Kennedy endoscope score than single plasma treatment group. There were significant differences between the two groups in the severity scores of VAS like rhinobyon, nasal stuffy, rhinocnesmus and running nose(P<0.05), and the differences in the severity scores of VAS like mycteroxerosis, nasal pain, and nasal discomfort were also significant(P<0.05). Sequential surgery group was markedly lower in the total VAS score than single plasma treatment group. Conclusion Both groups have obtained satisfactory efficacy in the treatment of hypertrophic rhinitis. There is no significant difference between the two groups in objective Lund-Kennedy endoscope evaluation score. According to subjective VAS evaluation, sequential surgery group is evidently better than single plasma treatment group in clinical efficacy. Inferior nasal concha sequential surgery has excellent clinical efficacy in the treatment of chronic hypertrophic rhinitis, and also has significant advantages in protecting the physical function of inferior nasal concha and avoiding patients’ postoperative subjective discomfort.

Objective To study the effect of curcumin in combination of resveratrol on proliferation in the head and neck neoplasm cell lines. Methods Hep2 cells and FaDu cells were treated with Curcumin and resveratrol. MTT was used to determine cell proliferation. Colony formation was used to detect the cell viability. Hoechst 33258 staining was performed to observe the cell apoptosis. The mRNA expressions of Bax and Bcl-2 were analyzed by Real-time PCR. Results Hep2 and FaDu cell proliferation could be inhibited with curcumin and resveratrol in a dose-dependent manner. Their combination exhibited the best inhibitory effects. Curcumin combined with resveratrol exhibited colony repression and showed a more significant apoptosis in Hep2 and FaDu cells. Real-time PCR demonstrated that Bax mRNA was upregulated and Bcl-2 mRNA was downregulated by curcumin and resveratrol. Meanwhile, Bax mRNA was upregulated and Bcl-2 mRNA was downregulated by curcumin and resveratrol. Conclusion The combination of curcumin and resveratrol can inhibit the proliferation of Hep2 and FaDu cells more significantly. The potential mechanism may be related with the up-regulation of Bax and the down-regulation of Bcl-2.

Objective To analyze the clinical characteristics and diagnostic points of 18 patients with laryngeal tuberculosis. Methods The clinical data of 18 patients with laryngeal tuberculosis were retrospectively analyzed in Tianjin First Center Hospital. Results The major manifestations of laryngeal tuberculosis include hoarseness, sore throat, foreign body sensation in the throat, dysphagia, hemoptysis and cough, but the general symptoms were not obvious. The throat was characterized by pale swelling, proliferative nodules, and ulcerative erosion. According to the results of chest computed tomography(CT)or X radiography, 10 patients had pulmonary tuberculosis, but did not receive anti-tuberculosis treatment. One of 9 patients undergoing sputum smear acid-fast staining was shown positive. Through pathological examination, 6 out of 14 patients were found gram-positive bacteria, and the positive rate was 42.9%. There was 1 patient with laryngeal tuberculosis and laryngocarcinoma after all the diagnosed patients were given anti-tuberculosis treatment in Tuberculosis Dispensary. Conclusion Laryngeal tuberculosis is closely related to lung tuberculosis, and is easily caused by the respiratory tract of patients with pulmonary tuberculosis in Tianjin. Laryngeal tuberculosis tends to be missed diagnosis and misdiagnosed due to atypical general symptoms. Pathological biopsy under the fibrolaryngoscope or general anesthesia should be taken as a major method to make the accurate diagnosis.

Objective To investigate the influence of propylene glycol mannate sulfate(PGMS)on the expression of vascular endothelial growth factor(VEGF)in diabetic retinopathy(DR)by a rat model, to study the mechanism of PGMS againstDR, and to provide a reliable theoretical and experimental evidence for the PGMs to be applied to clinical prevention and treatment of DR. Methods Male Wistar rats were randomized into the normal control group, the diabetic control group and the PGMS group. The PGMS group was subdivided into the low-dose PGMS group and high-dose PGMS group, with doses of 50 mg/kg and 100 mg/kg, respectively. The 1% Streptozotocin(STZ)of 60 mg/kg was intraperitoneally injected in rats to establish the diabetic models. The PGMS with the doses of 50 mg/kg and 100 mg/kg were used to gavage in different groups of models for 12 weeks. Twelve weeks later, the animals were sacrificed and retinas were isolated. The aqueous humor and serum were taken, expressions of VEGF protein in retina, aqueous humor and serum were detected by ELISA, respectively. The location and the expression of VEGF protein in 山东大学耳鼻喉眼学报31卷2期 -周玮琰,等.甘糖酯对糖尿病大鼠视网膜病变中血管生成因子VEGF表达的影响 \=-retina tissue was detected by immune-histochemistry. Real-time RT-PCR was used to measure the expression of VEGF mRNA in retinas. Results Twelve weeks after the use of PGMS,the level of blood glucose was not changed. ELISA showed that the expression of VEGF protein in serum was not significantly changed in different groups(P>0.05), but the expression of VEGF protein in aqueous humor and retina was significantly increased in diabetic control group than normal control group(P<0.05), but the groups which PGMS was given reduced, lower than that DM group, showing statistically significant differences(P<0.05). Immunohistochemistry showed that the VEGF protein was almost not expressed in normal control group, but the VEGF protein was highly expressed in diabetic control group. The expression mainly located in the ganglion cell layer, the inner plexiform layer, outer nuclear layer. The VEGF protein was weakly expressed at the group of PGMS. Real-time RT-PCR showed the expression of VEGF mRNA was lower in normal control group. The expression of VEGF mRNA in diabetic control group was almost 2.12 times than normal control group. The expression was decreased obviously in the group of PGMS. Conclusion PGMs has a good control effect on early diabetic retinopathy. PGMS can treat the diabetic retinopathy by downregulating the expressions of VEGF in early diabetic retinopathy.

Best corrected visual acuity(BCVA)and highest thickness of macular edema of the two groups were observed. Results One months after treatment, BCVA of the two groups were improved(P<0.05). No significant difference between two groups was found in the highest thickness of macular edema(P>0.05). Conclusion Ranibizumab intravitreal injection can improve visual acuity and reduce the highest thickness of macular edema in patients with CSME and NCSME. The highest thickness of macular edema can not completely reflect the visual acuity.

Objective To establish and validate the regression formula of intraocular pressure(IOP)by analyzing the influencing factors of IOP following laser assisted in situ keratomileusis(LASIK). Methods A prospective case study was performed on 235 myopia patients receiving LASIK. After self-contrast of randomized paired design, the influencing factors of IOP noncontact tonometer(IOP_NCT)were analyzed. The multiple regression formula to forecast the changes of IOP_NCT after LASIK was established and verified. Results The preoperative IOP_NCT was not related to gender, dominant eye, age or keratometry of the patients(P>0.05), but positively related to the central corneal thickness(CCT)and absolute value of spherical equivalent. The IOP_NCT changes after LASIK(△IOP_NCT)were not related to age, keratometry or stroma bed thickness of the patient(P>0.05), but positively related to the preoperative IOP_NCT, CCT, ablation depth, ablation rate(AR)and absolute value of spherical equivalent. The multiple linear regression formula of the IOP_NCT changes after LASIK was: △IOP_NCT = IOP_NCT-preop×0.552 + AR×0.158-6.219(R2=0.561, P<0.01). After Verification by practical cases, there was no statistically significant difference between the estimated values and measured values of the IOP_NCT changes after LASIK(t=-0.129, P=0.897). Conclusion The IOP_NCT of pre-LASIK is not related to gender, dominant eye, age or keratometry of the patient, but positively related to the central corneal thickness and absolute value of spherical equivalent. The △IOP_NCT is not related to age, keratometry or stroma bed thickness of the patient, but positively related to the IOP_NCT of pre-LASIK, central corneal thickness, absolute value of spherical equivalent, ablation depth and rate. The values of △IOP_NCT can be estimated by the regression formula.

Objective To evaluate the efficacy and safety of EX-PRESS implantation(EX-PRESS)compared with trabeculectomy(Trab)in open-angle glaucoma(OAG). Methods Databases including PubMed, EMbase, CNKI, VIP and WanFang Data were electronically searched for all randomized controlled trials(RCTs)about comparing the efficacy and safety between EX-PRESS implantation and trabeculectomy in open-angle glaucoma before the date of March 31, 2016. Two reviewers independently screened literature according to the inclusion and exclusion criteria, and evaluated the included studies. Then, meta-analysis was performed using RevMan5.3 software. Results A total 7 RCTs involving 447 patients with 462 eyes were included, 234 eyes in the EX-PRESS group and 228 eyes in the Trab group. The results of meta-analysis showed that there was significant difference between EX-PRESS and Trab in the postoperative 6 months and 1 year IOPR% ［WMD=-7.67, 95%CI(-14.85, -0.50), P=0.04］ and ［WMD=11.38, 95%CI(1.55, 21.22, P=0.02］, there was no significant difference between EX-PRESS and Trab in 24 months and end of follow-up after surgery IOPR%. The pooled OR was ［OR=2.29, 95%CI(1.27, 4.13), P=0.006］ comparing EX-PRESS with Trab for the complete success rate at one year after surgery and there was no significant difference between Ex-PRESS and Trab in the qualified success rate at one year after surgery ［OR=1.59, 95%CI(0.73, 3.44), P= 山东大学耳鼻喉眼学报31卷2期 -王越,等.EX-PRESS引流器植入术与小梁切除术治疗开角型青光眼有效性和安全性的Meta分析 \=-0.24］ and the number of anti-glaucoma medication ［WMD=-0.10, 95%CI(-0.36, 0.17), P=0.48］. But postoperative 2 year visual acuity ［WMD=-0.12, 95%CI(-0.23,-0.00), P=0.04］ had difference compared EX-PRESS with Trab. The pooled ORs of shallow or flat anterior chamber, hypotony, encapsulated bleb, wound leak, and choroidal effusion respectively was ［OR=1.43, 95%CI(0.71, 2.87), P=0.32］, ［OR=1.03, 95%CI(0.54, 1.96), P=0.94］, ［OR=0.25, 95%CI(0.05, 1.25), P=0.09］, ［OR=0.96, 95%CI(0.35, 2.64), P=0.94］, and ［OR=0.69, 95%CI(0.28, 1.72, P=0.43］ compared EX-PRESS with Trab. But EX-PRESS compared to Trab, with pooled ORs of hyphema ［OR=0.13, 95% CI(0.04, 0.42), P=0.0006］. Conclusion Trab had a better effect in IOPR% at 6 months after surgery, but EX-PRESS had a better effect in 1 year after surgery. But EX-PRESS surgery complete success rate was higher and EX-PRESS was associated with a significantly lower frequency of the hyphema compared to trabeculectomy. Moreover, Trab got better recovery of visual acuity. And there was no difference in the number of anti-glaucoma medication for the people need medications control the IOP between the two surgeries.

Chronic rhinosinusitis(CRS)is a common inflammatory disease. TJs are the most apically located of the intercellular junctional complexes, and may have critical role in barrier function of epithelium. Found in the recent years, the changes of tight junctions(TJs)may play important roles in the pathogenesis of chronic rhinosinusitis. The component of TJs are the spot-light in current area of research. This review article explores the pathogenesis of CRS, especially the tight junctions, for the sake of further understanding of CRS.

Sinonasal mucosal malignant melanoma(SMMM)is a rare sinonasal malignant tumor. Due to the atypical symptoms, most patients were diagnosed as the advanced stage, and the 5-year survival rate is limited to 20%-30%. Pathology is the gold standard for diagnosis. Black pigment particles found in the tissue cells can help the diagnosis; for the non-pigmented melanoma, immunohistochemistry can help to identify the diagnosis. Compared with Ballantyne staging, the 7th edition of American Joint Committee on Cancer(AJCC)malignant melanoma tumor node metastasis(mmTNM)staging may be more suitable for SMMM. At present, the surgical treatment is the first choice for early SMMM, and a comprehensive treatment method, such as surgery combined with radiotherapy and biochemotherapy is favorable to improving the survival rate of patients.
