Abstract? AIM: To analyze the ocular manifestations of meningiomas in the trigone of the lateral ventricle, discuss the relevant factors of visual impairment in these patients and things need attention clinically.?METHODS:Retrospectively study on the clinical data of 90 eyes in 45 patients diagnosed of trigonal meningiomas treated at Beijing Tian Tan Hospital from October 2011 to October 2015.Preoperative examinations including visual acuity, optic disc findings, visual field, size of tumors and other change in MRI were analyzed.?RESULTS: Patients'age was 12-68 years old ( mean 41.7 ±13.7 years ). Male/female ratio was 1 ∶4.6. Decreased visual acuity occurred in 18 eyes.Optic disc edema was found in 24 eyes and optic disc pale in 6 eyes. Fourty -seven eyes had visual field defect, mostly homonymous hemianopia or defect. The maximum diameter of tumors was 2.1-9.6cm (4.8±1.7cm).Range of tumor volume was 3.02-193.2cm3(48.3±47.8cm3).A positive correlation of preoperative visual field defect was found with tumor volume, tumor maximum diameter, and brain midline shift respectively. While the preoperative visual field defect was not found any correlation with age, gender, course, and the enlargement of the ventricle and the edema of the tissue around the tumors. After Mann-Whitney U test, the differences on tumor volume, the maximum diameter of tumors, and brain midline shift between the two groups were significant.? CONCLUSION: Patients with trigonal meningiomas often have ocular signs and symptoms.The major reason of visual field defect is the damage of optic radiation around the tumor.The specific position of injured optic radiation determines the type and extent of visual field defect.Both ophthalmologist and neurosurgeon should pay attention to tumors nearby posterior visual pathway. Doing neurophthalmology examinations for these patients and realizing the position between the tumor and posterior visual pathway will be helpful and necessary in surgical planning.

Background The rat model of N-methyl-N-nitrosourea (MNU)-induced photoreceptor cell apoptosis is often used to study retinal degeneration.But the changes in the gene expression patterm in retinal degeneration in rats have not been reported.Objective This study was undertaken to investigate regulation of gene expression in the retina of MNU-induced retinal degeneration in rats by performing microarray analysis of retinal RNA.Methods Fifty 6-week-old SD rats were numbered and randomized into the normal group and the model group.The retinal degeneration model was established by a single hypodermic injection of 40 mg/kg of MNU,and the rats in the normal group received equivalent volume of physiological saline in the same way.The rats were sacrificed 12 hours or 24 hours after injection.Retinal sections from the right eyes were prepared for the measurement of the retinal thickness by histopathological examination,and retinas from the left eyes were used to confirm the differential gene expression as detected by microarray (normal group and 12 hours model group).Genes exhibiting changes in expression by ≥2.0 folds were further confirmed using real-time PCR.Results The whole thickness of the retina declined in the rats from the 24 hours model group compared to the normal group and 12 hours model group (t =9.926,P=0.002;t=2.736,P=0.028).The thickness of the outer nuclear layer was (26.58±2.90) μm in the 24 hours model group,showing a significant decrease in comparison with (38.11 ± 1.01) μm in the normal group and (35.07t3.03) μm in the 12 hours model group (t=6.028,P=0.009;t=6.839,P=0.006).However,there was no significant difference in retinal thickness between the normal group and the 12 hours model group (whole thickness:t=1.541,P=0.324;outer nuclear layer thickness:t=2.040,P=0.134).Microarray analysis of the rat genes showed that out of 17 000 genes,142 genes involved in biological process and 94 genes involved in molecular functions were differentially expressed,where most of them participate in the mitogen activated protein kinase signaling pathway,Tolllike receptor signaling pathway and apoptosis pathway.Real-time PCR analysis demonstrated that the expression of CCL2,IL-1b,CCL3,c-fos,c-myc,p53 and MMP3 were consistently up-regulated,conforming with the results from microarray analysis.Conclusions The changes in gene expression pattern appear in the early stage of MNUinduced retinal degeneration.These microarray results provided clues to understanding the molecular pathways underlying photoreceptor degeneration and indicating the directions for future studies.

OBJECTIVETo explore the effect of Danggui Yinzi (DY) on delayed allergy in model mice with qi-blood deficiency syndrome (QBDS).
METHODSQBDS model was established in 48 Kuming mice of SPF grade by using reserpine and acetophenone hydrazine. Forty of them were then randomly divided into the model group, the loratadine group, the high dose DY group, the middle dose DY group, and the low dose DY group, 8 in each group. Another 8 in line with the same standard were recruited as a blank group. Mice in high, middle, and low dose DY groups were administered with DY concentrated solution at 60, 30, 15 g/kg by gastrogavage. Mice in the loratadine group were administered with loratadine solution at 1.66 mg/kg by gastrogavage. Equal volume of normal saline was administered to mice in the model group and the blank group by gastrogavage. All medication was given once per day for 1 successive week. Except those in the blank group, the rest mice were evenly smeared with 1% DNCB solution on the abdomen. Five days after skin allergy, 1% DNCB solution was smeared to right ear of all mice to stimulate allergic reaction. Mice in the blank group were smeared in the same way without allergenic reaction. The auricle swelling and the inhibition ratio were determined at 24 h after attack. Blood was collected from orbit and serum IgE level detected using double-antibody sandwich ELISA.
RESULTSCompared with the blank group, auricle swelling obviously increased and serum IgE level was obviously elevated in the model group (P < 0.01). Compared with the model group, auricle swelling obviously decreased and serum IgE level was obviously reduced in the 3 dose DY groups (P < 0.05, P < 0.01). Meanwhile, the auricle swelling degree was superior in high and middle dose DY groups to that in the loratadine group (P < 0.05). The inhibition ratio of auricle swelling was sequenced from high to low as 67.3% in the high dose DY group, 56.0% in the middle dose DY group, 48.1% in the low dose DY group, 47.3% in the loratadine group.
CONCLUSIONSDY could inhibit auricle swelling and lower serum IgE level. It also could inhibit delayed allergic reaction in model mice with QBDS to some extent.

AIM:To evaluate the optic nerve and axon impairment of relapsing - remitting multiple sclerosis ( RRMS) and neuromyelitis optica spectrum disorders ( NMOSD ) via detecting the peripapillary retinal nerve fiber layer (pRNFL) and the ganglion cell complex( GCC) thickness by optic coherence tomography(OCT).
METHODS: Retrospective case control study. Two hundred three cases were collected from August 2014 to January 2016 in Beijing Tian Tan Hospital. They were divided into four groups, including the normal group (n=60), the RRMS group ( n = 60 ), the NMOSD anti -aquaporin- 4 autoantibody seropositive( NMOSD- AQP4 -Ab seropositive) group (n= 48), and the NMOSD-AQP4-Abseronegative group (n = 35). All people were detected for the average and four quadrants ( superior, inferior, nasal, temporal) of pRNFL thickness and the average and two quadrants (superior, inferior) of GCC thickness with OCT. One way analysis of variance or nonparametric tests was used to compare the differences of pRNFL and GCC thickness between groups.
RESULTS: Comparing with the normal group, the average and all quadrants of pRNFL and GCC thickness in the RRMS, the NMOSD - AQP4 - Ab seropositive and the NMOSD-AQP4-Ab seronegative group were thinner (P<0. 01). Among them, the pRNFL and GCC thickness in the NMOSD- AQP4 - Ab seropositive group was the thinnest. Differences between groups in the pRNFL thickness:compared with the RRMS group, all quadrants of pRNFL and GCC thickness in the NMOSD-AQP4-Ab seropositive group were significantly thinner(P<0. 01); compared with the NMOSD- AQP4- Ab seronegative group, the inferior, nasal and temporal pRNFL thickness in the NMOSD-AQP4-Ab seropositive group were significantly thinner(P<0. 05), while the superior quadrant did not show significant differences( P > 0. 05); compared with the RRMS group, the superior pRNFL thickness in the NMOSD - AQP4 - Ab seronegative group was significantly thinner ( P < 0. 05), while the inferior, nasal and temporal quadrants did not show significant differences ( P > 0. 05 ). Differences between groups in the GCC thickness: compared with both the RRMS and the NMOSD- AQP4- Ab seronegative group, all quadrants of GCC thickness in the NMOSD -AQP4-Ab seropositive group were significantly thinner (P<0. 05); compared with the RRMS group, the superior GCC thickness in the NMOSD - AQP4 - Ab seronegative group was significantly thinner(P<0. 01), while the inferior quadrant did not show significant difference(P>0.05).
CONCLUSION: The optic nerve and axon impairment in NMOSD - AQP4 - Ab seropositive group was the most severe and the impairment in RRMS group was the least severe. The impairment in NMOSD - AQP4 - Ab seronegative group was between the former two, and could be more similar to that of RMMS.

Objective:
To understand the parenting styles of junior high school students in Beijing, to explore the relationship between parenting styles with students academic performance and the role of mental health in this association.
Methods:
From October 2019 to January 2020, a stratified random cluster sampling method was used to select 5 196 students in the first and second grades of 11 public junior high schools in urban and rural areas in Beijing, and Slort Egna Minnenar Barndoms Uppfostran-China,Middle School Students Mental Health Scale-60 and self designed questions were used in the questionnaire survey.
Results:
The average score of parenting style rejection dimension was (9.44±3.88), and the average score of emotional warmth dimension was (19.85±5.66). The average score of comprehensive score of students mental health was ( 1.92 ±0.73). Mental health score of girls was higher than boys (1.97±0.74)(1.87±0.71), and the differences were of statistical significance( t=5.06, P <0.01). Parental rejection and emotionally warm parenting styles were significantly correlated with students academic performance ( β =-0.54,1.15, P <0.01). Mental health played a negative moderating role between parenting style and students academic performance. The better students mental health were, the greater the influence of parenting style on academic performance.
Conclusion
Parenting style is related to children s academic performance. Parents should give their children more affirmation, encouragement and praise, in order to improve their academic performance.
