ABSTRACT
Objective To evaluate the dose response and prognosis of patients with stage ⅠE primary ocular adnexal mucosa associated lymphoid tissue lymphoma (POAml) treated with radiotherapy.Methods Clinical date of 93 patients (117 eyes) with stage ⅠE POAml treated from November 2003 to July 2015 were retrospectively analyzed.The dose response was evaluated by observing the ocular changes in exophthalmos.The survival rate was calculated by using the Kaplan-Meier survival analysis.The log-rank test and univariate analysis were used for prognostic analysis.Results For patients treated with a dose of ≥ 27 Gy,the response rate of exophthalmos was 69.0%(29/42).The median response dose was 7.2 Gy (5.4-19.8 Gy).For all patients,the local control rate was 100%.The 5-and 10-year overall survival (OS) rates were 92% and 82%.The 5-and 10-year cause-specific survival (CSS) rates were equally 98%.The 5-and 10-year progression-free survival (PFS) rate were 90% and 88%.The univariate prognostic analysis demonstrated that the International Prognostic Index (IPI) score and age were the prognostic factors of PFS rate (both P=0.04).Conclusions POAml is sensitive to radiation therapy.Radiotherapy alone can yield excellent local control and long-term survival in POAml patients.A prescription dosage of 18 Gy dose can obtain favorable clinical efficacy.
ABSTRACT
Objective To investigate CT,clinical and pathological features of primary pulmonary lymphoepithelioma-like carcinoma (LELC). Methods The clinical,CT and pathological data of 22 patients with pulmonary LELC confirmed by pathology were analyzed retrospectively, including 8 males and 1 4 females whose ages were from 1 8 to 88 years old.Results Among 22 cases,1 2 patients were found by physical examination,2 patients had cough and sputum,7 patients had cough hemoptysis and 1 patient was found by re-examination after breast cancer surgery.On CT,all cases manifested single mass in the lung,and the longer diameters ranged from 1.5 cm to 1 1 cm,in which there were central type tumors in 8 cases and peripheral type tumors in 14 cases.Nineteen masses showed homogeneous density in non-enhanced scan,and the cavity,irregular calcification and small patchy necrosis were seen in each 1 case.After contrast-media injected,masses were mild-moderately or evidently enhanced in 7 cases and 1 5 cases respectively.Eighteen cases had well defined border and unclear border in 4 cases.Vascular encasement were found in 6 central type tumors,8 tumors squeezed peripheral vascular and 8 cases had clear demarcation between tumors and vascular.Nineteen tumors were surgically removed,in which 7 cases appeared metastasis of lymph node.Histopathology showed that the tumor cells had large volumes,unclear boundaries,large nuclei,growing in syncytial nest-like patches.There were abundant lymphocyte and plasma cell infiltration in tumor’s mesenchyma.EBER were done in 1 6 cases and the results were all positive.Conclusion CT feature of pulmonary LELC manifestes that the masses are mostly single,large size, homogeneous density,clearly boundary,shallow lobulated and significantly enhancement.Vascular encasement is the feature of central pulmonary LELC,and peripheral LELC is more likely to occur in the sub-pleural region.Final diagnosis should be combined with clinical and pathological diagnosis.
ABSTRACT
Objective@#To screen the differentially expressed long non-coding RNAs(lncRNAs) by analyzing the related gene sequencing data of female non-smoking lung cancer patients in the database of The Cancer Genome Atlas (TCGA). @*Methods@#The gene expression data and the corresponding clinical information of female non-smoking lung cancer patients were downloaded from the TCGA database. Then, the data were processed, integrated and analyzed with the R software package, and the differentially expressed genes were screened out. The prognosis was analyzed by the Survival package. @*Results@#A total of 354 differentially expressed lncRNAs associated with female non-smoking lung cancer were obtained, of which 45 were down-regulated and 309 were up-regulated in tumor tissues. The prognosis analysis showed that the expression level of LINC01863 was positively correlated with the prognosis of female non-smoking lung cancer patients (P<0.05), and that the expression levels of LINC02487, LINC01419 and DSCAM-AS1 were negatively correlated with the prognosis of female non-smoking lung cancer patients (P<0.05). @*Conclusion@#The re-analysis on the high-throughput sequencing data in TCGA database obtains a large number of lncRNAs related to the development of female non-smoking lung cancer, which provides the potential new targets for the diagnosis and prognosis assessment of female non-smoking lung cancer.
ABSTRACT
Objective To investigate the effect of rhynchophylline on mRNA expression of excitatory amino acid transporter 2 (EAAT2 ) and N-methyl-D-aspartic acid receptor 2B (NR2B) after astrocyte oxygen-glucose deprivation. Methods The subcultured third generation astrocytes from the hippocampus were inoculated into 6-well plates, and they were divided into blank control group, hypoxia-ischemia group,low-dose rhynchophylline group (0. 02 mg/ml) and high-dose rhynchophylline group (0. 2 mg/ml) after the cells were attached to the wall and grew out protrusion. The total RNAs in each group were extracted.Real-time fluorescence quantitative polymerase chain reaction was used to detect the expression levels of EAAT2 and NR2B mRNA in astrocytes of each group. Results Compared with the blank control group, the expression levels of NR2B and EAAT2 mRNA in astrocytes of the ischemia-hypoxia group were significantly higher (all P < 0. 05 ). The expression levels of NR2B and EAAT2 mRNA in the low-dose rhynchophylline group were lower than those in ischemia-hypoxia group, but there was no significant difference. The expression levels of NR2B and EAAT2 mRNA in the high-dose rhynchophylline group were significantly lower than the ischemia-hypoxia group and the low-dose rhynchophylline group (all P < 0. 05).Conclusion The expression of EAAT2 and NR2B mRNA in astrocytes of hippocampus cultured in vitro was significantly increased after ischemia and hypoxia, and rhynchophylline intervention could significantly reduce its expression in a concentration dependent manner.

ABSTRACT
Objective To analyze the X -ray, CT, and MR imaging findings in osteoid osteoma. Methods Forty-eight cases of osteoid osteoma proved by surgical pathology were collected, including 33 males and 15 females. Among the 48 cases, all patients had plane films, 32 were imaged with CT scanning, 10 with MR imaging, and 8 with all three techniques. The imaging findings of osteoid osteoma and the ability of X-ray, CT, and MRI in demonstrating the nidus and the surrounding reaction were analyzed. Results The imaging manifestations of osteoid osteoma revealed a circular or oval nidus with different bone sclerosis around the nidus. The diameters ranged from 0.4 cm to 1.7 cm, with the average of 9.7 cm. There were also soft tissue and bone morrow edema around the nidus or distinct effusion of joint on MR imaging in all 10 cases. Among 48 cases, only 37 cases showed nidus on plane film. All 32 cases with CT scanning showed nidus. The display ratios of nidus were 77% for X-ray and 100% for CT, respectively. 10 cases with MR imaging could be diagnosed correctly. But the nidus could be affirmed in only 8 cases, and the nidus was affirmed by comparing with plane film or CT in the other 2 cases. Conclusion Nidus is the key in diagnosing the osteoid osteoma correctly. Plane film is still an important checking method for osteoid osteoma. CT scan is the best method to demonstrate the nidus. MRI can demonstrate the soft tissue and bone morrow edema around the nidus sensitively, but probably lead to an incorrect diagnosis. Combining with X-ray or CT, MRI can make an accurate diagnosis.
ABSTRACT
Objective To study the application of standardized A/B ultrasonography for the orbital vascular lesions. Methods Standardized A/B ultrasonography was performed on orbital vascular lesions of 145 cases. Results The orbital vascular lesions included the cavernous hemangiomas in 79 cases, venous hemangiomas 19 cases, lymphangiomas 15 cases, infantile hemangiomas 5 cases, varix 12 cases and carotid-cavernous sinus fistula 15 cases. The positive rate of standardized A/B scans was 98.6 %, false negative 1.4 %.Conclusions Standardized A/B ultrasonography can make accurate diagnosis for orbital vascular lesions. B-mode ultrasonography mainly shows the shape, location and the relation to normal orbital structure, but A-mode ultrasonography is more accurate in internal reflectivity of lesions, and sound attenuation and quantitative. Combined B-mode and A-mode ultrasonography is more effective for diagnosis of orbital vascular lesions.

ABSTRACT
B-ultrasonography and/or CT scannings of 84 cases of enlarged superior ophthalmic vein (SOV) were analysed morphologically and etiologically. Carotid-cavernous fistula, ophthalmic Graves disease, Tolosa-Hunt syndrome, orbital vascular deformity, inflammation at the apex of the orbit, orbital pseudo tumor, intraorbital hematoma and thrombosis of the SOV might induce enlargement of SOV. Associated with other Findings of intraorbital tissues revealed by CT and B-ultrasonography, the etiological diagnosis of the enlarged SOV could be made. The dynamic findings of the SOV rendered by B-ultrasonography and Doppler ultrasonic play an important role in the diagnosis of carotid-cavernous fistula.
