Objective To evaluate the effectiveness of repeated intravitreal conbercept injection in patients with macular edema (ME) of retinal vein occlusion (RVO),guided by optic coherence tomography (OCT).Methods It is a retrospective case study.Forty patients (40 eyes) diagnosed as ME secondary to RVO were enrolled in this study.There were 19 males (19 eyes) and 21 females (21 eyes),with the mean age of (53.58 ± 13.19) years and the mean course of 1.5 months.The best corrected visual acuity (BCVA),indirect ophthalmoscopy,fundus fluorescein angiography (FFA) and OCT were performed.The mean baseline of BCVA,central macular thickness (CMT) were 0.25 ± 0.18 and (509.48 ± 170.13) μm respectively.All the patients were treated with 10.00 mg/ml conbercept 0.05 ml (including conbercept 0.5 mg).Follow-up of these patients was 1 to 6 months after treatments,the BCVA,fundus manifestations,OCT were retrospectively observed by every month,the FFA was retrospectively observed by every 3 months.When there was retinal edema or CMT ≥ 50 μm by OCT during follow-up,those patients were retreated with intravitreal conbercept injection.The changes of the BCVA,CMT were evaluated before and after treatment.Meanwhile,complications in eyes related to medicine and treatment methods were evaluated too.Results At the 6 months,the BCVA was improved (increase≥2 lines) in 25 eyes (62.50％),stabilized (± 1 line) in 13 eyes (32.50％) and decreased 2 lines in 2 eyes (5.00％).Retinal hemorrhage and exudates were absorbed in most patients.FFA showed no fluorescein leakage in 1 1 eyes (27.50％),minor fluorescein leakage in 26 eyes (65.00％),and retinal capillary non-perfusion in 3 eyes (7.50％).OCT showed absorption of the subretinal fluid.The mean CMT were (235.20± 100.44) μm at 6 months.Intravitreal injection of conbercept was applied for 4 times in 8 eyes (20.00％),3 times for 18 eyes (45.00％),and 2 times for 14 eyes (35.00％).The mean number of intravitreal injection was 2.85 times.There were no ocular or systemic adverse events observed in all patients.Conclusion Intravitreal conbercept injection is an efficacy and safe treatment for the patients with ME of RVO guided by OCT.It can stabilize and improve the visual acuity.

Objective:To investigate the correlation between hyperreflective dots (HRD) and lipid levels and systemic inflammatory factors in patients with branch retinal vein occlusion (BRVO) or central retinal vein occlusion (CRVO).Methods:A cross-sectional clinical study. From December 2016 to June 2020, 118 eyes of 118 patients with retinal vein occlusion diagnosed in the Department of Ophthalmology, Central Theater Command Hospital of People's Liberation Army were included in the study. Among them, 67 cases of BRVO and 51 cases of CRVO were divided into CRVO group and BRVO group accordingly. Peripheral venous blood was drawn from the patients within 3 days after the eye examination to detect the percentage of neutrophils, monocytes, hypersensitive C-reactive protein (CRP), total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and lipoprotein(a). The ratio of monocytes to high-density lipoprotein (MHR) was also calculated. The 3D OCT-2000 instrument from Topcon (Japan) was used to measure the central retinal thickness (CRT) and the numbers of HRD. According to the different distribution position, HRD is divided into inner retina HRD, outer retina HRD, and total retina HRD.The independent sample t test was used to compare the continuous variables of the two groups, and the χ2 test was used to compare the rates. The correlation between HRD counts and blood lipid levels and peripheral blood inflammation indicators in patients with different types of RVO was analyzed by Spearman correlation analysis. Results:The average age of patients in the BRVO group and CRVO group were 60.1±9.5 and 53.6±15.7 years, respectively; the prevalence of hypertension was 53.7% (36/67) and 24.5% (12/51), respectively. Comparison of age ( t=2.634) and prevalence of hypertension ( χ2=11.298) between the two groups showed statistically significant differences ( P<0.05). Gender ( χ2=2.000), course of disease ( t=-1.101), prevalence of diabetes ( χ2=1.315), eye category ( χ2=1.742), baseline visual acuity ( t=1.792), intraocular pressure ( t=0.708), CRT ( t=1.318), and peripheral blood include the percentage of neutrophils, the absolute number of monocytes, CRP, total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, lipoprotein(a), MHR ( t=-0.559, 1.126, 0.579, 1.299, -0.134, 0.556, 1.230, -0.267, 0.483), the difference was not statistically significant. Correlation analysis showed that the HRD counts in the outer retina of BRVO patients were positively correlated with total cholesterol ( r=0.289, P=0.036); the HRD in the inner retina and total HRD counts of CRVO patients were positively correlated with CRP ( r=0.406, 0.343; P=0.004, 0.014). There was no correlation between HRD counts and percentage of neutrophils, absolute number of monocytes, triglycerides, high-density lipoprotein, low-density lipoprotein, lipoprotein(a), and MHR ( P>0.05). Conclusion:The number of HRD is related to the blood lipid level in BRVO patients and CRP (an inflammatory index) in CRVO patients.

Objective To explore the relationship between IL-1?-511C/T and IL-1?+3953C/T site polymorphisms and the susceptibility of pediatric epilepsy.Methods Under the case-control study,IL-1?-511C/T and IL-1?+3953C/T site polymorphisms in 117 patients with pediatric epilepsy and 95 healthy individuals controls(healthy control group) were analyzed with polymerase chain reaction restriction and fragment length polymorphism(PCR-RFLP),the relationship between IL-1?-511C/T,IL-1?+3953 C/T site polymorphisms and the risk of pediatric epilepsy were analyzed.SAS 8.0 software was used to analyze the data.Results Multiple variate logistic regression analysis revealed that compared with healthy control group,there was no relationship between the IL-1?-511C/T site polymorphisms and the susceptibility of pediatric epilepsy individuals,carrying at least one +3953T variant allele(CT and TT genotypes) had a significantly increased risk for pediatric epilepsy(adjusted OR=2.46,95%CI 1.03-5.87),compared with the wild-type genotype(+3953CC).Furthermore,individuals with epilepsy or febrile seizures family history had a significantly higher risk(adjusted OR=4.12,95%CI 1.28-29.34),compared with those with both CC genotypes.Conclusions These findings support the hypothesis that IL-1?-511C/T site polymorphisms have no relationship with epilepsy,but the IL-1?+3953C/T polymorphism may contribute to the risk of developing pediatric epilepsy.

BACKGROUND: Bone marrow cell transplantation is a simple and effective treatment to promote angiogenesis. The neovascularization and reestablishment of blood circulation is crucial to the repair of injured but still living neurons as well as to the survival and differentiation of the implanted tissues and cells. However,it is not clearly known whether autologous bone marrow cells implantation could promote neovascularization and facilitate reestablishment of circulation in ischemic regions of the brain.OBJECTIVE: To investigate the effect of autologous bone marrow cell transplantation via the carotid artery on angiogenesis in the ischemic regions of the brain.DESIGN: A randomized controlled experiment based on experimental animals.SETTING: Department of neurosurgery and institute of urinary surgery in a university hospital.MATERIALS: The experiment was conducted in the Laboratory of the Department of Neurosurgery,Second Affiliated Hospital,and the Institute of Urinary Surgery,Jiangxi Medical College during the period from September 2002 to April 2003,using 10 specific pathogen-free male SD rats weighing 250 - 300 g.INTERVENTIONS: Rat models of focal cerebral ischemia model were established and randomized equally into two groups. The rats in the transplantation group were injected with autologous bone marrow cells via the carotid artery and those in the control group normal saline injection. The angiogenesis in the ischemic regions of the brain was observed with immunohistochemical staining for microvessel counting.MAIN OUTCOME MEASURES: The density of microvessels. Immunohistochemical staining for F8.RESULTS: Greater density of the microvessels was found in the ischemic regions after bone marrow cell transplantation than in the control group[(159. 15 ±40.4)/mm2 vs(81.70 ± 32. 18)/mm2,P ＜ 0. 05] . Numerous endothelial cells were found scattered in the ischemic cortex of the transplantation group,but scarcely in the control group.CONCLUSION: Autologous bone marrow cell transplantation via the carotid artery can promote angiogenesis in the ischemic regions of the brain.

Objective To identify the hairless gene mutations in a family of atrichia with papular lesions. Methods Skin biopsies were taken from typical lesions for histopathological examination. Genomic DNA was extracted from blood samples of the family members. Complete encoding sequences of hairless gene Dwere detected by polymerase chain reaction (PCR) and DNA sequencing. Results Compound heterozygous mutations were identified in the patient: G337D in exon 3 and Q498X in exon 4. There was only one of the mutations in his parents and a younger brother. Conclusions G337D and Q498X mutations in hairless gene seem to be responsible for the phenotypes in the patient suffered from atrichia with papular lesions.
