Objective To study and compare the clinical efficacy between intravitreal conbercept injection and (or) macular grid pattern photocoagulation in treating macular edema secondary to non-ischemic branch retinal vein occlusion (BRVO).Methods Ninety eyes of 90 patients diagnosed as macular edema secondary to non-ischemic BRVO were enrolled in this study.Forty-eight patients (48 eyes) were male and 42 patients (42 eyes) were female.The average age was (51.25 ± 12.24) years and the course was 5-17 days.All patients were given best corrected visual acuity (BCVA),intraocular pressure,slit lamp with preset lens,fluorescence fundus angiography (FFA) and optic coherent tomography (OCT) examination.The patients were divided into conbercept and laser group (group Ⅰ),laser group (group Ⅱ) and conbercept group (group Ⅲ),with 30 eyes in each group.The BCVA and central macular thickness (CMT) in the three groups at baseline were statistically no difference (F=0.072,0.286;P=0.930,0.752).Patients in group Ⅰ received intravitreal injection of 0.05 ml of 10.00 mg/ml conbercept solution (conbercept 0.5 mg),and macular grid pattern photocoagulation 3 days later.Group Ⅱ patients were given macular grid pattern photocoagulation.Times of injection between group Ⅰ and Ⅲ,laser energy between group Ⅰ and Ⅱ,changes of BCVA and CMT among 3 groups at 1 week,1 month,3 months and 6 months after treatment were compared.Results Patients in group Ⅰ and Ⅲ had received conbercept injections (1.20 ± 0.41) and (2.23 ± 1.04) times respectively,and 6 eyes (group Ⅰ) and 22 eyes (group Ⅲ) received 2-4 times re-injections.The difference of injection times between two groups was significant (P＜0.001).Patients in group Ⅱ had received photocoagulation (1.43 ±0.63) times,9 eyes had received twice photocoagulation and 2 eyes had received 3 times of photocoagulation.The average laser energy was (96.05 ±2.34) μV in group Ⅰ and (117.41 ±6.85) μV in group Ⅱ,the difference was statistical significant (P=0.003).BCVA improved in all three groups at last follow-up.However,the final visual acuity in group Ⅰ and group Ⅲ were better than in group Ⅱ (t=4.607,-4.603;P＜0.001) and there is no statistical significant difference between group Ⅲ and group Ⅰ (t=-0.802,P=0.429).The mean CMT reduced in all three groups after treating for 1 week and 1 month,comparing that before treatment (t=-11.855,-10.620,-10.254;P＜0.001).There was no statistical difference of CMT between group Ⅰ and Ⅲ at each follow up (t=0.404,1.723,-1.819,-1.755;P=0.689,0.096,0.079,0.900).CMT reduction in group Ⅰ was more than that in group Ⅱ at 1 week and 1 month after treatments (t=-4.621,-3.230;P＜0.001,0.003).The CMT in group Ⅲ at 3 month after treatment had increased slightly comparing that at 1 month,but the difference was not statistically significant (t=1.995,P=0.056).All patients had no treatment-related complications,such as endophthalmitis,rubeosis iridis and retinal detachment.Conclusions Intravitreal conbercept injection combined with macular grid pattern photocoagulation is better than macular grid pattern photocoagulation alone in treating macular edema secondary to non-ischemic BRVO.Combined therapy also reduced injection times comparing to treatment using conbercept injection without laser photocoagulation.

Objective To study the relativity between pathology and CT diagnosis and CT classified types of the golioma of the brain.Methods Seventy cases of golioma confirmed by CT diagnosis and pathology by way of non-contrast CT scanning and enhanced scans were analysed in comparison the results of the pathology and CT appearances.Results (1)The accuracy rate of CT diagnosis was 85.7%;(2)having pointed out the CT classified types of the golioma of the brain a acording of CT appearances comibined with shape.Type Ⅰ was(low-tensity,non-enhancement types)16 cases,which can be only seen in Ⅰ and Ⅱ grade of astrocytoma oligodendroglioma,and the latter was often characterized by bending stripe-like calcification or cluster dot-like calcification,both of which occupy 33% of the total (3/9).Type Ⅱ was (ring-like enhanced patterns)13 cases,which often appeared in Ⅱ?Ⅲ?Ⅳ grade astrocytoma,charactenied by parietal-node which took up 53.8%(7/13).The pathology changes were mainly caused by the internal neceosis and a few by cystic changes.Type Ⅲ(nodular or mass-like enhancement) in 31 cases revealed by various types of goliomsas,which were typical CT appearances of medulloblastoma and ependymoma.Type Ⅳ(mixed types)in 10 cases had showed the CT appearances of malignant goliomas.(3)The results indicate that no or slight edema and mass effect as well as intensification were mainly seen in Ⅰ and Ⅱ grade astrocytomas,Ⅲ and Ⅳ grade astrocytomas were classified as the less serious and the serious both of which had distinctive differences.(4)Analyse the CT appearances of brain golioma in terms of tumor cytology had provided the pathology evidences for CT classified patterns.Conclusion CT appearances and CT classified patterns can reflect some pathologie characteristics and provide an important reference for astrocytoma pathology grading.

OBJECTIVETo observe the effect of natural borneol on the permeability of blood tumor barrier (BTB) model and the expression and activation of mitogen-activated protein kinase (MAPKs) signal transduction pathway related protein kinase in vitro.

METHODSC6 rat glioma cells and human umbilical vein endothelial cells (HUVECs) were co-cultured to establish BTB model. Then 4 groups were set up, the blank control group, low, middle, and high dose borneol groups (25, 50, 100 µg/mL), 3 samples collected at 7 time points (0, 10, 30, 60, 120, 180, 240 min, respectively). Blank culture medium was exchanged in the blank control group while medication. Different doses of natural borneol were administered to the 3 borneol groups. Cells were collected at different time points. BTB permeability was determined using horseradish peroxidase (HRP). Expression levels of extracellular signal regulated protein kinase (ERK), phosphorylation extracellular signal regulated protein kinase (P-ERK), P38MAPK, phosphor-P38MAPK, c-Jun N-terminal kinase (JNK), and phosphorylation c-Jun N-terminal kinase (P-JNK) were detected using Western blot.

RESULTSCompared with the same group at min 0, the permeation rate obviously increased (P < 0.01) in the 3 borneol groups at the rest time points. P-ERK expression was elevated first, reached the peak at 30 min, and gradually recovered to the initial level (P > 0.05). Compared with the blank control group, HRP permeation rate increased from 10 min to 240 min (P < 0.01), and expression of P-ERK protein increased at 30 min and 60 min (P < 0.05) in the low dose borneol group; expression of P-JNK protein decreased in the 3 borneol groups at 180 min and 240 min (P < 0.05). Compared with the low dose borneol group, expression of P-ERK protein increased from 10 min to 180 min (P < 0.05), HRP permeation rate increased from 30 min to 180 min (P < 0.05), expression of P-JNK protein decreased at 180 and 240 min (P < 0.05) in the middle dose borneol group. Compared with the middle dose borneol group, HRP permeation rate increased from 10 min to 180 min (P < 0.05), expression of P-ERK protein increased from 10 min to 180 min (P < 0.05), expression of P-JNK protein increased at 180 min and decreased at 240 min (both P < 0.05) in the high dose borneol group.

CONCLUSIONNatural borneol arrived at the effect of regulating reversible BTB patency possibly through activating phosphorylation of ERK in MAPKs signal transduction pathway, and further reversibly down-regulating expression of associated proteins.
