Objective To investigate the common complications related to glomus jugulare tumors surgery,their influencing factors,and to search for the effective treatments of these complications.Methods A retrospective study was undertaken on the complications observed in 47 patients with glomus jugulare tumors who underwent 51 times of operation via trans external auditory canal approach,the retroauricular approach,and modified infratemporal fossa approach type A.All cases were followed up over 1 month after surgery.Results Of 51 cases,the most frequent complication was total conductive hearing loss which occurred in 21 cases(41.2%),facial paralysis was found in 15 cases(29.4%) and lower cranial nerve palsy was found in 14 cases(27.5%) after one month.Other complications were cerebrospinal fluid(CSF) leak,hearing disability and vertigo,each in 3 cases(5.9%);cerebral infarction,partial auricle necrosis and parotid gland fistula,each occurred in one case(2.0%).Pre-operative selective embolization of feeding vessels can reduce intraoperative blood loss significantly in most cases.Effective hemostasis and hypotensive anesthesia during operation were the important ways to prevent complications and hematoma within operating field.CSF leak in this series was an uncommon complication.Two cases with CSF leak from the wound had been successfully controlled with conservative treatment.One case with CSF leak required surgical management.None of these patients developed meningitis.Conclusions There is a low level of serious post-operative complications in operation on glomus jugulare tumor.Factors found to be relevant to post-operative complications are tumor type and tumor size.The key factors to avoid the complications include surgical experience,surgical skill and preoperative evaluation of patients′ imaging information.

Objective　To review the anatomic and visual outcomes of a series of patients with macular holes who underwent vitreous surgery without adjunctive therapy.Methods　We performed a retrospective review of 16 patients who underwent vitrectomy, fluid-gas exchange and perflu oropropane(C3 F8) gas temponade for 14 eyes with idiopathic and 2 eyes with traumatic macular holes.Results　Anatomical closure of the macular holes was achieved in 15(93%) of 16 eyes with an average follow-up of 7 months. Only one eye needed performing second surgery. Three(19%) eyes achieved postoperative visual acuity of 0.4, four (25%)eyes 0.2～0.3,and nine(56%)eyes 0.1 or worse. Conclusions　Vitreous surgery without adjunctive therapy with intraocular gas tamponade and postoperative posturing is a well tolerated and effective intervention for idiopathic or some traumatic macular holes. Anatomical closure of the macular hole is associated with a significant improvement in visual acuity in most eyes.

Objective To explore clinical value of transvagiTIa ultrasound in diagnosis of cctopie oviductpregnancy.Methods EUB-2000 ultrasound diagnosis meter was used,the vagina probe head frequency is 5～10MHz,after the vagina to the womb,the double-side ovary,the double side oviduct and its periphery organizes to carry on omni-direetionally sweeps looks up.Results Transvagina ultrasound diagnosis ectopic pregnancy center oviduct pot abdomen pregnancy 158 cases,the oviduct canyon department 4 cases,between the oviduct the nature department pregnancy 2 cases,all pass through the cefioseope of our hospital.Coincidence rate was 100%.Conclusion Transvagina ultrasound diagnosis ectopie pregnancy is one of most accurate ultrasound diagnosis methods presendy,suggested various basic units hospital widely develops.

Objective:To study the strategy of endovascular treatment for patients with the risks of internal carotid artery (ICA) rupture and bleeding during the treatment of nasopharyngeal carcinoma (NPC) based on American Society of Intervention and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR) grade of collateral circulation.Methods:A total of 56 patients (45 males and 11 females, aged from 28 to 76 years old) diagnosed with nasopharyngeal carcinoma and admitted to the Department of Neurosurgery, the Third Affiliated Hospital of Southern Medical University from July 2018 to January 2020 were retrospectively analyzed. There were 15 cases of ASITN/SIR grade 4, 24 cases of ASITN/SIR grade 3, 5 cases of ASITN/SIR grade 2, 5 cases of ASITN/SIR grade 1, and 7 cases of ASITN/SIR grade 0. The events of stroke and death were analyzed statistically.Results:ALL patients with ASITN/SIR grade 4 or 3 and some of patients with ASITN/SIR grades 2-0 passed balloon occlusion test and electrophysiological monitoring. ICA pseudoaneurysm was found in 35 patients, and one-stage ICA embolization was performed in 29 patients after evaluation. Among them, 8 cases of ASITN/SIR grade 4 and 10 cases of ASITN/SIR grade 3 with obvious posterior circulation compensation obtained successful one-stage ICA embolization without cerebral ischemia; cerebral ischemic events occurred in 5 (55.6%) of 9 patients with ASITN/SIR grade 3 and in 1(50.0%) of 2 patients with ASITN/SIR grade 2. The total incidence of ischemic events was 20.7% (6/29) and 1 case was disabled (1/29, 3.4%). Among patients with ASITN/SIR 3, there were statistically significant differences in stroke event rate between patients with obvious posterior circulation compensation and patients with slight or without posterior circulation compensation (0/10 vs. 5/9, χ 2=4.95, P=0.026). Follow-up time was 10.1±7.8 months, and 46 patients were survival (46/56, 82.1%) and 10 patients died (10/56, 17.9%) with a mean survival time of 2.6±1.4 months. Conclusions:For NPC patients with ICA invasion, ASITN/SIR based on DSA can simplify the assessment process of cerebral blood flow compensation. ICA can be embolized directly in patients with ASITN/SIR 4 or 3 with obvious posterior communicating compensation.

Objective The role of this essay is to explore the relationship of BIM deletion polymorphism and paclitaxel intrinsic resistance in breast cancer. Methods Human breast cancer cell lines were screened by techniques of PCR and gene sequencing to detect BIM deletion polymorphism.MTS was used to detect the cytotoxic effects of paclitaxel in different cell lines. Meanwhile,levels of BIM mRNA and protein were detected by rtPCR and Western Blot. Results Comparing with the wild type cell line(MCF7),T47D was a deletion cell line with BIM deletion polymorphism and resistant to paclitaxel(T47D vs.MCF-7,IC50>30le vs.IC50=0.16 vs.02 μmol/L). Moreover,the ratio of BIM EXON3 to EXON4 was significantly increased and the level of functional BIM protein was down-regulated in T47D compared with MCF7(P < 0.05). Conclusion BIM deletion polymorphism might initiate intrinsic resistance to paclitaxel therapy in breast cancer.
