Uveitis is a kind of inflammatory disease affected in ocular posterior segment.Uveitis sustains a long duration and causes a significant damage of visual function.It often leads to serious complications,such as cystoid macular edema (CME),cataract,glaucoma,retinal detachment and choroidal neovascularization (CNV).In the pathological process of uveitis,inflammatory factors promote the release of vascular endothelial growth factor (VEGF) through a variety of pathways.It has been verified that VEGF level is elevated in vitreous in the patients with uveiticinduced CME.Intravitreal injection of anti-VEGF drugs,including ranibizumab and bevacizumab,can improve the visual acuity in most patients with noninfectious uveitic-induced CME and CNV.However,intravitreously repeated injections of anti-VEGF drugs may be required in some patients.Intraocular injection of anti-VEGF drugs is an optional and effective way for those with persist macular edema and not being suitable for the use of corticosteroid or immunosuppressive therapy.However,anti-VEGF drugs may affect the efficacy of corticosteroid.Therefore,more clinical and basic researches are still needed.The status and progresses in the use of anti-VEGF drugs for uveitisinduced CME and CNV were reviewed.

Objective To investigate the effect of methylprednisolone pulse therapy on spinal nerve functions in patients with acute spinal cord injury (ASCI) and evaluate its safety. Methods 200 patients with ASCI treated in our hospital from January 2010 to December 2016 were selected and were randomly divided into two groups,with 100 cases each group. The patients in control group were treated with routine basic treatment while patients in the study group were treated with methylprednisolone pulse therapy. On the basis of the American spinal cord injury Society scoring criteria (ASIA), the neurological functional recovery scores were performed were scored before and 6 weeks after treatment between the two groups and the adverse reactions were recorded. Results The scores of sensory and motor function of the patients in the two groups were higher than those before the treatment and there was statistical difference (P<0.05), and the scores in the study group was significantly higher than those in the control group, and the difference between the two grouPs was statistically significant (P<0.05). The incidence of adverse reactions in the study group (25.00％) was significantly higher than that in the control group (10.00％), and the difference was statistically significant (P<0.05). The incidence of lung infection and gastrointestinal reaction in the study group were significantly higher than those in the control group and there were statistical difference (P<0.05). Conclusion Methylprednisolone pulse therapy has significant effect on the recovery of neurological function in patients with ASCI, but the incidence of adverse reactions is high, so it is necessary to strengthen the monitoring and intervention in clinic.

Objective To investigate the expression and distribution of COX-2 in benign and malignant breast disease,and the relationship among COX-2 expression and the clinicopathologic factors,hormone receptors.Methods Immunohistochemistry Was used to investigate the expression and distribution of COX-2 in 8 accessory.breasts,31 BPBDs(15 in adnosis,16 in fibroadnoma),70 IDCs(35 of them accompany with DCIS);The relationships between the expression of COX-2 and hormone receptor(ER and PR),C-erbB-2.and the clinicopathologic factors were studied respectively.Results①The expression of COX-2 in various kinds mammary diseases:8 accessory breasts were all negative;the positive rate of COX-2 in BPBD was 96.5%(30/31),among these,the positive rate of COX-2 in adnosis was 93.3%(14/15),and in fibroadnonm was 100%(16/16).The positive rate of COX-2 in DCIS was 85.7%(30/35).The intensity of COX-2 expression in DCIS of periph-IDC was higher than that in corresponding carcinoma.The positive rate of COX-2 in IDC Was 84.3%(59/70),the expression of COX-2 Was different among non-cancer gland.②COX-2 expression in BPBD was obviously higher compared with COX-2 in IDC,the difference was significant in statistics(χ2=9.39,P＜0.025).③The expression of COX-2 in DCIS was correlative with low histological differentiation(χ2=10.98,P＜0.005),PR negative(P=0.019,Fisher exact probability),and C-erbB-2 positive(P=0.0008,Fisher exact probability).The expression of COX-2 in IDC was correlative with lymph node metastasis(χ2=4.09,P＜0.05),tissue poorly differentiated(P=0.004,Fisher exact probability),PR negative(χ2=6.91,P＜0.01)and C-erbB-2 positive(χ2=5.94,P＜0.025).Conclusion COX-2 does not express in normal mammary gland.It is high-expressed in BPBD,DCIS and IDC;These indicate the up-regulation of COX-2 expression not only participates in breast carcinogenesis,but also promotes its metastasis and progression,and suggests COX-2 may down-regulate reactivity of endocrine thempy by participating in therapy resistance of PR negative breast cancer.

Objective To explore the related structures of retrosigmoid approach by microanatomy and virtual anatomy and provide a reliable approach with more morphologic data. Methods Twenty sides of 10 adult cadaveric heads were dissected to simulate retrosigmoid approach under the microscope. The neurovascular structures of pontocerebellar trigone were observed, and the related structures were simultaneously measured based on the junction of superior petrosal sinus and sigmoid sinus and internal acoustic pore. The internal auditory canal was opened by drilling the margin of the internal auditory meatus and its structures were watched. With the help of Dexotroscope system, the data of five patients' CT and MRI were applied to reconstruct and anatomize the structure of retrosigmoid approach. Results It was found that the distance from the junction of superior petrosal sinus and sigmoid sinus to the trigeminal nerve was (38.50±2.64)mm, to the acoustic-facial bundle (27.80±2.25)mm, to the glossopharyngeal nerve (32.70±2.11)mm, to the hypoglossal nerve (44.30±2.05)mm, and the distance from internal acoustic pore to the trigeminal nerve was (5.68±1.55)mm, to the abducent nerve (13.80±1.81)mm, to the tentorium of cerebellum (5.00±0.66)mm, to the glossopharyngeal nerve (6.34±1.24)mm. The pontocerebellar trigone was divided into the anterior compartment, the middle compartment, the posterior compartment built on the acoustic-facial bundle and the glossopharyngeal nerve. Their structures were displayed after drilling the margin of the internal auditory meatus. Dexotroscope system clearly displayed asterion, the angle of transverse and sigmoid sinus, jugular foramen, internal acoustic pore, basilar artery and its branches, and theirs spatial relationship.Conclusion The three compartments of the pontocerebellar trigone are helpful to understand the feature of the neurovascular layer, the measurement is favorable to quantize the relation of the related structures and to judge the space of each compartment. Recognizing the anatomical marker of internal acoustic pore can support preservation of the inner structures. Virtual anatomy of Dexotroscope system can display local anatomical structure respectively. Both microanatomy and virtual anatomy have their advantages and disadvantages respectively and integration can be beneficial to understand neurovascular structures in the pontocerebellar trigone.

Objective To investigate the clinical manifestations and pathogen distribution of the neonatal sepsis, and to analyze the antibiotic resistance of the pathogens. Methods Review the Medical records of 38 sepsis cases of full-term and premature neonates in our hospital from October 2011 to February 2014 were col-lected and analyzed. Results Ten cases were caused by Gram-positive bacteria among the 18 full-term neonates with sepsis. Eight of ten of the isolates were resistant to oxcillin. Nine of ten of the cases were belonged to late onset infection, and the cases with no nosocomial infection were found. In the other eight full-term neonatal cases caused by Gram-negative bacteria , six cases were nosocomial infection. Among the 20 premature neonates with sepsis , 17 cases were infected Gram-negative bacteria , in which Escherichia coli , Klebsiella pneumonia and En-terobacter cloacae were the most common agents (16/17). Early onset type and nosocomial infection were identi-fied for 11 (11/20) and 9 (9/20) cases in the premature neonates, respectively. The penicillin G, methicillin resistant rates of the Gram-positive bacteria were close to or over 70%. All the Gram-positive bacteria were sensi-tive to vancomycin. All the Gram-negative bacteria were resistant to amoxicillin , but over 60% of them were sen-sitive to piperacillin-tazobactam and other compounds containing enzyme inhibitor , and 100% of them were sensi-tive to carbapenems and aminoglycoside. Conclusion The full-term neonatal sepsis admitted into our hospital were mainly caused by Gram-positive bacteria , which were usually resistant to oxcillin. The premature sepsis were mainly caused by Gram-negative bacteria , which were always sensitive to carbapenems and aminoglycoside.
