A young female complained repeated nasal discharge for over three months with discomfort of right cheek, and oral antibiotics had less effect. She has a history of "root canal therapy" five years before. Physical examination found purulent secretion in the right middle nasal meatus, and light tenderness in the right side of the maxillary sinus area. The CT scan of paranasal sinus shown possible fungal infection of right maxillary sinus. Finally the nasal endoscopic surgery confirmed the fungus ball of right maxillary sinus with foreign body (the root canal filling material).

Objective To investigate the inhibition effect of plasma-mediated small interfering RNA (siRNA) on the expression of monocyte chemotacite protein-1 (MCP-1) gene in human renal tubular epithelial cells (HKC).Methods Three pairs of siRNAs directed human's MCP-1 mRNA 67,116,142 targets were designed and synthesized.Eukaryotic expression vector special for MCP-1,pRNAT-MCP-1-Ⅰ、pRNAT-MCP-1-Ⅱ、pRNAT-MCP-1-Ⅲ were constructed and transfected into HKC by lipofectamine.At 24 hour after transfection,the expression of MCP-1 in the levels of mRNA was detected by Real Time RT-PCR,and the expression of MCP-1 in the levels of protein was detected by Western blot.Results Transfection efficiency of siRNA expression vector was 60%;the expression of MCP-1 in the levels of mRNA and protein of three pairs of plasma-mediated siRNA group were markedly decreased compared with normal control group(P

AIM: To investigate the difference of cognitive impairment and depression between age-related macular degeneration ( AMD ) group and the control group patients. ·METHODS: A prospective case-control study was performed from November 2014 to August 2016 in the hospital for AMD patients and sex-matched control group. The Mini-Mental State Examination ( MMSE) and the Geriatric Depression Scale ( GDS ) score of each patient were collected for statistical analyzing. ·RESULTS: There were total 84 cases ( 168 eyes ) included in the study. The difference of visual acuity between the two group was statistically significant ( F=8. 953, P=0. 004) by baseline data analyzing. There were no significant differences in MMSE scores between the two groups according to educational status ( P>0. 05 ) , while the prevalence of cognitive impairment in each group was statistically significant (x2 =4. 14, P=0. 042). The difference of GDS scores, prevalence of total and mild depression between two groups were both statistically significant (F=5. 852, P=0. 018; x2=6. 372, P=0. 012; x2 = 5. 674, P = 0. 017 ). However, there was no statistically significant difference in the prevalence of moderate to severe depression (x2=0. 672, P=0. 412). ·CONCLUSION: AMD patients have a higher prevalence of depression. Although MMSE score differences were not statistically significant in subgroup analysis by educational levels, AMD patients are more likely to have cognitive impairment overall.

Objective To discuss the effect of gene transfection of rAAV2/1-NPY-EGFP on KA-induced rat seizures,EEG and the expression of hippocampal phosphorylated Tau protein.Methods Altogether 72 healthy male Wistar adult rats were randomly divided into three groups:control group,KA group and NPY group(n=24).The epileptic models were established by the injection of KA 2 μl (0.4 μg/μl) five times to the right side of the hippocampus CA3 area every three days.rAAV2/1-NPY-EGFP group,in which 10 μl of rAAV2/1-NPY-EGFP (titer 5× 1011 v.g./ml) was injected to the lateral ventricle in successful rats chronic model,while KA group was injected with an equal dose of saline.The control group was injected with an equal dose of saline both in the hippocampal CA3 area and the lateral ventricle.The seizure situation,the onset latency and EEG were observed at 2 weeks and 4 weeks after vector injection.Then the expression of phosphorylated Tau protein in hippocampus were detected with Western blotting.Results (1) Scale and latency of each seizure onset in rats of rAAV2/1-NPY-EGFP group (12.13 ± 8.06) had no significant difference at 2 weeks (P＞ 0.05) compared with KA group (12.10± 8.07).The scale of seizure in rats of rAAV2/1-NPY-EGFP group(6.06±3.78) significantly reduced at 4 weeks(P ＜0.05).Latency of seizure onset (79.06±8.83min) significantly increased at 4 weeks(P＜0.05),EEG epileptic discharge frequency and wave amplitude decreased (P＜ 0.05) at 4 weeks.The control group had no seizures.(2)Compared with the control group,the expression of phosphorylated Tau protein in KA group and NPY group significantly increased(P＜0.05) at 2 weeks and 4 weeks,and the expression of phosphorylated Tau protein in the NPY group (1.15±0.16 RQ value) at 4 weeks significantly decreased (P＜0.05) compared with the KA group(1.87± 0.23 RQ value).Conclusion rAAV2/1-NPY-EGFP gene transfection significantly reduces scale of seizure onset and prolongs latency of seizure onset in KA-induced rat model.rAAV2/1-NPY-EGFP gene transfection may play anti-epileptic and neuroprotective effects through inhibiting the expression of phosphorylated Tau protein in hippocampus of KA-induced epileptic rat model.

Objective To investigate the effect of CDH1 3'-UTR + 54C/T single nucleotide polymorphism(SNP) on expression of luciferase reporter gene and its association with susceptibility to cervical cancer. Methods The luciferase gene expression vectors containing CDH1 3'-UTR +54C/T SNP C or T allelotype were constructed. The effect of CDH1 3'-UTR + 54C/T SNP on expression of luciferase reporter gene in 293 T cells were tested by daul lucfferase reporter assay system. The CDH1 3'-UTR + 54C/ T SNP was genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis in 280 cervical cancer patients and 330 healthy controls. Results The lucfferase activity analysis showed that the relative luciferase activity (RLA) of 293T cells with C allelotype was 1.46, which was significantly lower than that of the 293 T cells with T allelotype (3.01; t=2. 94, P =0. 042). There was no significant difference in age distribution between the cervical cancer patients and the healthy controls. The genotype frequency distribution of CDH1 3 '-UTR + 54C/T SNP in healthy controls did not significantly differ from that expected by Hardy-Weinberg equilibrium (P>0.05). The C allelotype frequency of CDH1 in cervical cancer patients was 80. 7%, which was significantly higher than that in healthy controls (74. 5%;χ2 =6.59, P=0.010). The T/T, T/C and C/C genotype frequencies of cervical cancer patients and healthy controls were 4. 3%, 30. 0%, 65. 7% and 5. 8%, 39. 4%, 54. 8%, respectively, which were significandy different (χ2=7.45, P =0.024). Compared with individuals with T/T or T/C genotypa, individuals with C/C genotype had significantly higher risks of developing cervical cancer (OR = 1. 578,95%CI=1.136 -2.191). Conclusion The C allelotypa of CDH1 3'-UTR + 54C/T SNP might decrease the expression of lucfferase reporter gene and the C/C genotypa might be a potential risk for cervical cancer development.
